Which came first the first seed or first plant with seed?
If you consider evolution, then plants with seeds came from plants without seeds. So, the first plant with seed evolved from a olant without seed and then gave rise to the first seed. That means first seed came from first plant with seed.
How did seeds come to be?
Before we explain how seeds came to be, it’s important to note one basic fact about plants. Land plants evolved from ocean plants. That is, from algae. Plants are thought to have made the leap from the oceans onto dry land about 450 million years ago.
What is the oldest seed in the world?
The oldest seed that has grown into a viable plant was a Judean date palm seed about 2,000 years old, recovered from excavations at Herod the Great 's palace on Masada in Israel. It had been preserved in a cool, dry place, not by freezing.
What happened between 450 million years ago to the first seeds?
And, as seeds are thought to have developed to keep plant embryos from drying out, it makes sense that the first seeds we know of are at least 360 million years old. But what happened between 450 million years ago and 360 million years ago? This gap of about 100 million years indicates that some method of (land) plant reproduction predated seeds.
Who came first seed or fruit?
Answer: Spores contain a single cell, whereas a seed contains a multicellular, fertilised embryo that is protected from drying out by a tough coat. These extra features took another 150 million years to evolve, whereupon the first seed-bearing plants emerged. So plants came first, by a long way.
What came first the tree or the seed?
The seed starts to grow after it gets wet. It then can grow into a tree. If you want to know how this happens you can look at this article. Trees make seeds, which can then grow into other trees.
What was the first plant to grow on Earth?
Cooksonia is often regarded as the earliest known fossil of a vascular land plant, and dates from just 425 million years ago in the late Early Silurian. It was a small plant, only a few centimetres high. Its leafless stems had sporangia (spore-producing structures) at their tips.
Where did the seed came from?
In the typical flowering plant, or angiosperm, seeds are formed from bodies called ovules contained in the ovary, or basal part of the female plant structure, the pistil.
When did seeds first appear?
about one million years agoSeed plants appeared about one million years ago, during the Carboniferous period. Two major innovations were seeds and pollen. Seeds protect the embryo from desiccation and provide it with a store of nutrients to support the early growth of the sporophyte.
Are seeds alive?
Although seeds are dormant (resting) their cells are still alive and performing typical cellular functions. Answer 3: Seeds are living! They are just typically in a dormant state, which means they require very little of the resources necessary to stay alive, until they are in the appropriate conditions to grow.
What did Earth look like before trees?
Long Before Trees Overtook the Land, Earth Was Covered by Giant Mushrooms. From around 420 to 350 million years ago, when land plants were still the relatively new kids on the evolutionary block and “the tallest trees stood just a few feet high,” giant spires of life poked from the Earth.
How old is the earth?
4.543 billion yearsEarth / Age
What was the first animal on Earth?
comb jellyEarth's first animal was the ocean-drifting comb jelly, not the simple sponge, according to a new find that has shocked scientists who didn't imagine the earliest critter could be so complex. The mystery of the first animal denizen of the planet can only be inferred from fossils and by studying related animals today.
How did the first seed start?
That is, from algae. Plants are thought to have made the leap from the oceans onto dry land about 450 million years ago. And, as seeds are thought to have developed to keep plant embryos from drying out, it makes sense that the first seeds we know of are at least 360 million years old.
How did the first seed come?
Scientists believe that an extinct seed fern, called Elksinia polymorpha, was the first plant to use seeds. This plant had cup-like features, called “cupules”, that would protect the developing seed. These cupules grew along the plant's branches.
Do seeds expire?
Most vegetable seeds will last through their expiration date if kept cool, dry and away from sunlight. Baker Seed guarantees seeds for at least two years after purchase. Most seeds last three to five years after purchase, but those dates can vary depending on the variety.
Where did the first tree come from?
Evolutionary history The earliest trees were tree ferns, horsetails and lycophytes, which grew in forests in the Carboniferous period. The first tree may have been Wattieza, fossils of which have been found in New York State in 2007 dating back to the Middle Devonian (about 385 million years ago).
What came out of the seed?
In botany, the radicle is the first part of a seedling (a growing plant embryo) to emerge from the seed during the process of germination. The radicle is the embryonic root of the plant, and grows downward in the soil (the shoot emerges from the plumule).
What does first seed mean?
NBA Seeds. In the NBA, seeds are determined solely by a team's record or win percentage. In each conference, the top 8 ranked teams, according to records, make the playoffs. The team with the best record earns the 1 seed, the next best team gets the 2 seed, and so on.
How did seeds come to be?
Before we explain how seeds came to be, it’s important to note one basic fact about plants. Land plants evolved from ocean plants. That is, from algae. Plants are thought to have made the leap from the oceans onto dry land about 450 million years ago.
What are some seedless plants?
On the other side of the spectrum, there are many “seedless” plants alive today, including ferns and horsetails – found in damp environments – as well as many aquatic plants. Our thanks to: Sir Peter Crane, Dean. Yale School of Forestry and Environmental Studies. Yale University.
What were the two types of spores that were produced during the Devonian period?
During Earth’s Devonian period, a group of plants called progymnosperms started manufacturing two sets of specialized spores: male spores, and female spores – the living tissues inside these spores produced eggs and sperm. Both types of spores were shed from the plant.
Where did the first plant seed come from?
The first plant seed came from the sea ,A long ago every creature lived in sea,even the plant.one time one creature came to understand how to live and that creature taken the carbon dioxide and with the help of sunlight and water it started to prepare it's own food and released some waste product that is oxygen. (so,by this we can understand that plants also do same like that,so now we can clearly tell that that creature is none other than plant.so,the first plant seed came from the sea by a cell.
What did plants reproduce like before seeds?
First you have to know that before seeds evolved, plants reproduced like ferns, where spores germinated into sperm which swam to the female ovule.
What is the theory of evolution?
According to Darwin's theory of evolution, all organisms have evolved from some previous organism. Also, there are many plants that don't have seeds. If you consider evolution, then plants with seeds came from plants without seeds. So, the first plant with seed evolved from a olant without seed and then gave rise to the first seed. That means first seed came from first plant with seed. The same is true for many other organisms. For ex- The chicken came before the egg, and then laid an egg.
Which fern has the closest resemblance to seed plants?
Seed plants arose from ancestral ferns. The extant fern today that bears closest resemblance in DNA sequences to seed plants is the fern Marsilea. https://en.wikipedia.org/wiki/Marsilea
Is the parent first than the child?
Simple logic to understand it, parents are first than kids so same logic applies for plants and seeds, as per this plants are first than seeds.
Do seeds co-evolve?
The crucial point to remember is simply that seed-bearing plants and seeds co-evolve.
What are the first colonisers?
Typically the first colonisers are microbes, then lichens and mosses, then herbaceous plants, shrubs and trees.
Where would vegetation have most easily become established?
The places where vegetation would most easily have become established were those furthest away from the highlands, such as low-lying plains and deltas. Here the energy of rainstorms and discharges of subterranean water was mostly dissipated. Tectonic processes in the mountains, coupled with the weathering effects of acid rain (at a time when there was much more carbon dioxide in the atmosphere), had already done the hard work of converting hard rock into grains. The successful plants were those suited to wetland environments, comparatively simple in design. They did not require mature soils. Disseminating their spores in the water, they reproduced quickly and proliferated over wide areas.
What is the diploid phase of moss?
The diploid phase is the short-lived result of self-fertilisation and grows on top of the plant, until it releases haploid spores and the cycle starts again. How this system came to be is of course unknown, and how mosses and liverworts fit into the evolutionary tree of life is unknown.
Where did mosses come from?
Spores of mosses and liverworts are known from at least the mid Ordovician onwards, less certainly from the Cambrian, and their abundance increases with ascending stratigraphic level, as one would expect if plant fossils were reflecting the progressive recovery of vegetation. Macrofossils before the Devonian are also scarce because conditions were unfavourable for their preservation. In particular, the Ordovician-early Silurian was a time of persistently high sea-levels, leaving few continental deposits. Many of the earliest spores occur in nearshore marine deposits, blown out to sea by the wind.
How did the new land form?
New land still forms today, and the way it forms is essentially the same as the way it formed in the Proterozoic and Palaeozoic. New seafloor was volcanically generated at mid-ocean ridges and, to compensate, old seafloor was subducted beneath continental plates. Water rising from the oceanic plate as it sank into the mantle lowered the melting point of the rock above it and caused magma to rise to the surface, erupting to form volcanic mountains, such as the Rockies and Andes. These added mass to the continental margin, some of the mass eroded into the sea and combined with sediments that were being scraped off the subducting oceanic plate, and over time the area of the continental margin grew.
What are the first organisms to build communities?
Bacteria, fungi and algae are the first to build communities. They release chemicals which break the rock into grains. Carbon dioxide dissolved in rainwater creates a weak acid which reacts with the rock minerals, washing some away in solution and turning the residue into clay.
How long did the new earth remain unstable?
The new earth remained unstable for thousands, even tens of thousands, of years. Ecological systems had to recover from scratch, in an uphill struggle where attempts at recovery were repeatedly being disrupted. It was in this context that we see the first plants appear in the fossil record.
Which tree was the first to grow?
Archaeopteris, the best known example, was the first modern tree. Being only slightly younger than Eospermatopteris, it was virtually the first tree. It had an extensive root system, produced leaves, grew to a height of 30 metres or more, and had laterally growing branches.
What were the plants that were part of the early ecosystem?
Almost from the first, the plants were members of small, mixed communities, rather than isolated pioneers. Springtails, spiders, insects, centipedes and millipedes played their part in the fledgling ecosystems.
Where did horsetails come from?
Horsetails go back to the Late Devonian and rapidly diversified. They already comprised three orders when they peaked in abundance in the Late Carboniferous. Like the arborescent lycopods, they grew as tall as trees, and produced secondary tissue only on the inside of the cambium.
What was the rise of plants in the Devonian period?
The rise of plants in the Devonian was a step change. In addition to the mosses and marsh vegetation of the previous period, now every major plant type was present. Extraordinarily complex organs and tissue systems appeared as if from nowhere. It was a ‘novelty radiation’ rather than a slow accumulation of infinitesimally small changes: stems with an intricate fluid transport mechanism, lignin, structural tissues, pores for controlled gas exchange (stomata, although mosses also have them), leaves and roots of various kinds, diverse spore-bearing organs (sporangia), seeds.
How did bifacial cambiums reproduce?
The innovation of a bifacial cambium enabled them to produce wood (secondary xylem) and thereby grow outwards as well as upwards, in the same way as trees do today. Unlike the later-appearing gymnosperms, to which they were probably ancestral, they reproduced by means of spores rather than seeds.
What record did fossils record?
This is the last in a 10-part series arguing that fossils record the Earth’s recolonisation after a mass extinction near the very beginning of history. Species that survived multiplied and diversified, the land was progressively reconstituted, and its repeatedly disturbed and buried surfaces were revegetated. Appearing in much the same order as in modern ecological successions, the first plants grew in swampy settings. Here we recount how low-lying plants were soon complemented by soaring forests.
Where does sporopollenin occur?
Sporopollenin occurs in the cell walls of some green algae and is the main polymer forming the tough outer walls of plant spores. Within plants, major innovations such as stomata, sporangia, leaves, roots and wood tissues all arose more than once. Leaves arose at least five times, perhaps as many as nine.
Which tree holds the record for the oldest directly dated seed to be germinated?
... Though a few trees have been planted from seeds that are rumored to be older than the Masada ones, the Methuselah tree holds the record for the oldest directly dated seed to be germinated.
How old is the date seed?
Israeli doctors and scientists have succeeded in germinating a date seed nearly 2,000 years old. The seed, nicknamed Methuselah, was taken from an excavation at Masada, the cliff fortress where, in A.D. 73, 960 Jewish zealots died by their own hand, rather than surrender to a Roman assault.
Where did the oldest date palm grow?
The oldest mature seed that has grown into a viable plant was a Judean date palm seed about 2,000 years old, recovered from excavations at Herod the Great 's palace on Masada in Israel. It had been preserved in a cool, dry place, not by freezing. It was germinated in 2005. ( For more details refer to Judean date palm: Germination ...
What is the oldest carbon-14 dated seed?
The oldest carbon-14 -dated seed that has grown into a viable plant was Silene stenophylla (narrow-leafed campion), an Arctic flower native to Siberia. Radiocarbon dating has confirmed an age of 31,800 ±300 years for the seeds. In 2007, more than 600,000 frozen mature and immature seeds were found buried in 70 squirrel hibernation burrows 38 metres ...
Where is sacred lotus grown?
Sacred lotus (Nelumbo nucifera) has been cultivated as a crop in Asia for thousands of years. An ~1300-yr-old lotus fruit, recovered from an originally cultivated but now dry lakebed in northeastern China, is the oldest germinated and directly 14C-dated fruit known.
Where did land plants originate?
Evidence of the earliest land plants occurs much later at about 470Ma, in lower middle Ordovician rocks from Saudi Arabia and Gondwana in the form of spores with decay-resistant walls.
How did land plants evolve?
The closest living relatives of land plants are the charophytes, specifically Charales; assuming that the habit of the Charales has changed little since the divergence of lineages, this means that the land plants evolved from a branched, filamentous alga dwelling in shallow fresh water, perhaps at the edge of seasonally desiccating pools. However, some recent evidence suggests that land plants might have originated from unicellular terrestrial charophytes similar to extant Klebsormidiophyceae. The alga would have had a haplontic life cycle. It would only very briefly have had paired chromosomes (the diploid condition) when the egg and sperm first fused to form a zygote that would have immediately divided by meiosis to produce cells with half the number of unpaired chromosomes (the haploid condition). Co-operative interactions with fungi may have helped early plants adapt to the stresses of the terrestrial realm.
What is the evolution of plants?
The evolution of plants has resulted in a wide range of complexity, from the earliest algal mats, through multicellular marine and freshwater green algae, terrestrial bryophytes, lycopods and ferns, to the complex gymnosperms and angiosperms (flowering plants) of today. While many of the earliest groups continue to thrive, ...
How many generations does angiosperm have?
Further information: Alternation of generations. Angiosperm life cycle. All multicellular plants have a life cycle comprising two generations or phases. The gametophyte phase has a single set of chromosomes (denoted 1n) and produces gametes (sperm and eggs).
When did fungi first appear?
The fungi were of the phylum Glomeromycota, a group that probably first appeared 1 billion years ago and still forms arbuscular mycorrhizal associations today with all major land plant groups from bryophytes to pteridophytes, gymnosperms and angiosperms and with more than 80% of vascular plants.
Is a land plant haploid or diploid?
The algal ancestors of land plants were almost certainly haplobiontic, being haploid for all their life cycles, with a unicellular zygote providing the 2N stage. All land plants (i.e. embryophytes) are diplobiontic – that is, both the haploid and diploid stages are multicellular.
How far below the permafrost were the seeds found?
The mature and immature seeds, which had been entirely encased in ice, were unearthed from 124 feet (38 meters) below the permafrost, surrounded by layers that included mammoth, bison, and woolly rhinoceros bones.
How old is the oldest plant?
32,000-Year- Old Plant Brought Back to Life—Oldest Yet. Feat may help scientists preserve seeds for the future. The oldest plant ever to be regenerated has been grown from 32,000-year-old seeds—beating the previous recordholder by some 30,000 years.
What is the oldest plant ever to be regenerated?
The oldest plant ever to be regenerated has been grown from 32,000-year-old seeds —beating the previous recordholder by some 30,000 years. (Related: "'Methuselah' Tree Grew From 2,000-Year-Old Seed.")
What temperature do palm seeds freeze?
stenophylla seeds' permafrost environment. Regenerating seeds that have been frozen at 19 degrees Fahrenheit (-7 degrees Celsius) for so long could have major implications, said Solowey, who was not involved in the new study.
Who was the father of the other seed?
Adam was the father of one seed, and Satan the father of the other seed.
What would happen if Jesus told the multitudes that Satan had biological children on earth?
If Jesus would have just plainly told the multitudes that Satan had biological children on earth and pointed out exactly who they were, it would have caused an uproar, probably severely damaging the message he was bringing.
Was Cain the firstborn son?
Additionally, though Cain was the firstborn son, it appears as though he was never considered to be the chosen seed of the woman. Check it out:
Is the serpent's seed a family line?
If the woman’s seed is a biological family line, then the serpent’s seed MUST also be a biological family line. To say otherwise would be wholly inconsistent with Gen.3:15.
Who is Cain's biological father?
Indeed, this appears to be a HUGE obstacle. And I would stop here and say, “Well, that solves it. No more needs be said. Adam is Cain’s biological father. Plain and simple.”
Was Abel the seed of the woman before Cain killed him?
Abel then was the original Seed of the Woman before Cain killed him. That means Cain was never of the woman’s seed. Think of this, if Cain and Abel were both of the woman’s seed, then she would have given birth to “two promised seeds” before Cain murdered Abel and there would be no serpent seed.
