Which group of plants is the most diverse and evolved most recently?
angiospermsFossil and molecular clock evidence agree that angiosperms are the most recently evolved of the major groups of plants. Both bodies of evidence also agree that the clade diverged from their sister group the gymnosperms, the cone-bearing plants (“Angiosperms,” 2008).
What are diverse plants?
Plant diversity refers to the existence of wide variety of plant species in their natural environments. There are around 300,000-500,000 species of vascular plants that exist on earth (Figure 1). This course covers: Understand plants and the basis of their classification.
What is the diversity of plants called?
BiodiversityBiodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi.
What is the most abundant group of plants on Earth?
angiospermsThe most abundant and diverse plants on Earth are the angiosperms, the flowering plants.
Where is plant diversity the highest?
Researchers have found the island of New Guinea is home to more than 13,000 plant species. This means it has the greatest plant diversity of any island in the world. 68% of these plants are endemic to New Guinea.
What are the 4 types of diversity?
There are generally four different types of diversity: internal, external, organizational, and worldview—and you should aim to understand and represent them all. Keep reading to learn more about each one and how diversity affects the workplace.

Why are plants so diverse?
One reason for this diversity is the close relationship they have with one another. Over many years, some flowers and pollinators have influenced each other's evolution. Today, when flower-pollinator pairs have traits that work very well together, it's a sign this kind of evolution may have happened.
What is diversity of plants and animals called?
Biodiversity is all the different kinds of life you'll find in one area—the variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural world. Each of these species and organisms work together in ecosystems, like an intricate web, to maintain balance and support life.
Why are angiosperms more diverse than gymnosperms?
The wind pollinated gymnosperms needed large contiguous populations for effective pollination. The coevolution of angiosperms and their pollinators has greatly increased the diversity of angiosperms.
Why are angiosperms the largest group?
Angiosperms are the largest plant group because it this the most evolutionarily developed and adapted group. They hide and protect their seeds in fruits, this also allows them to spread.
Which of the following groups is most abundant and most diverse on Earth?
The prokaryotes are by far the most abundant organisms inhabiting planet Earth. They are also by far the most diverse, both metabolically and phylogenetically; they encompass the Bacteria and the Archaea, two out of the three major divisions of living organisms.
What is an example of diverse?
The definition of diverse is different. An example of diverse is a classroom full of students from many different cultural backgrounds. Made up of distinct characteristics, qualities, or elements.
Why are plants diverse?
One reason for this diversity is the close relationship they have with one another. Over many years, some flowers and pollinators have influenced each other's evolution. Today, when flower-pollinator pairs have traits that work very well together, it's a sign this kind of evolution may have happened.
What are the 4 types of plants?
Types of Plants-Herbs, Shrubs, Trees, Climbers, and Creepers.
Why is diversity important in plants?
There is consistently strong evidence that strategically increasing plant diversity increases crop and forage yield, wood production, yield stability, pollinators, weed suppression and pest suppression (Table 1).
