How do plants take in oxygen and carbon dioxide?
Instead of taking in oxygen and breathing out carbon dioxide like animals do,plants take in carbon dioxide from the atmosphere. Plants absorb water from the ground up through their roots. During photosynthesis, the energy from the sun splits the water molecules into hydrogen and oxygen.
How do plants and animals get carbon?
Plants and animals get this element from carbon dioxide present in the atmosphere. Plants take carbon dioxide from air and in the presence of water and sunlight they make their food by the process of photosynthesis. Plants are consumed by other animals as food. In this way they get compounds of carbon.
What is the role of carbon in the environment?
Carbon is an essential element found in all living beings. Plants and animals get this element from carbon dioxide present in the atmosphere. Plants take carbon dioxide from air and in the presence of water and sunlight they make their food by the process of photosynthesis. Plants are consumed by other animals as food.
How is water formed in photosynthesis?
Water is formed by the combination of oxygen and hydrogen. During photo synthesis hydrogen is produced by the dissociation of water which forms glucose after combing with carbon dioxide. Plants provide food for herbivores and these animals get glucose and proteins from plants only.

Where do plants obtain oxygen?
We've seen that plants can obtain oxygen through photosynthesis, stomata, and root hairs. But unlike animals, plants do not have a specialized respiratory organ system for gas exchange.
Where do plants obtain carbon and energy?
Plants need energy from the sun, water from the soil, and carbon from the air to grow. Air is mostly made of nitrogen, oxygen, and carbon dioxide. So how do plants get the carbon they need to grow? They absorb carbon dioxide from the air.
Where do plants get the carbon?
The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun's energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.
Where do plants get the oxygen and hydrogen atoms they need?
In essence, green plants take carbon, hydrogen and oxygen from the molecules of carbon dioxide and water, and then recombine them into a new molecule called glucose. This happens in the presence of sunlight, of course.
Do plants get carbon from soil?
Our results indicated that although the majority of plant C was obtained from atmosphere by photosynthesis, a significant portion (up to 3–5%) of C in plant roots was derived from old soil.
How do plants absorb carbon?
As plants and trees grow, they take carbon dioxide from the atmosphere and turn it into sugars through photosynthesis. In this way, U.S. forests absorb 13 percent of the nation's carbon emissions; globally, forests store almost a third of the world's emissions.
Where do plants get most of their carbon dioxide?
Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata. (One of these holes is called a stoma. The plural is stomata.
Where do plants get their energy from?
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
Do plants need oxygen or carbon dioxide?
Plants need both carbon dioxide and oxygen for survival.
In what form do plants take in carbon?
carbon dioxidePlants take in – or 'fix' – carbon dioxide from the atmosphere during photosynthesis. Some of the carbon is used for plant growth, and some of it is used in respiration, where the plant breaks down sugars to get energy.
Where do plants get their nitrogen from?
Plants cannot themselves obtain their nitrogen from the air but rely mainly on the supply of combined nitrogen in the form of ammonia, or nitrates, resulting from nitrogen fixation by free-living bacteria in the soil or bacteria living symbiotically in nodules on the roots of legumes.
How does carbon become part of the soil?
Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years. Carbon moves from living things to the atmosphere.
Where do plants obtain their energy?
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
Where do the plants get energy from?
Plants rely on the energy in sunlight to produce the nutrients they need.
How do plant cells obtain energy?
In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose. In mitochondria, through the process of cellular respiration breaks down sugar into energy that plant cells can use to live and grow.
What is the source of energy for plants?
3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.
How do plants get carbon?
Carbon is an essential element found in all living beings. Plants and animals get this element from carbon dioxide present in the atmosphere. Plants take carbon dioxide from air and in the presence of water and sunlight they make their food by the process of photosynthesis. Plants are consumed by other animals as food. In this way they get compounds of carbon. Energy is produced by digestion of these carbon compounds. Carnivores get carbon from flesh of herbivores. Omnivores like man get carbon from both plants and animals. Carbon cycle shows that all the animals absorb carbon dioxide directly from atmosphere or from the plants. Animals convert carbon into carbon dioxide during respiration or oxidation and again this carbon dioxide is released into the air. Carbon dioxide is also liberated during decay of plants and animals and burning of fuels which enters into the atmosphere and completes carbon cycle.
Where do carnivores get their carbon?
Carnivores get carbon from flesh of herbivores. Omnivores like man get carbon from both plants and animals. Carbon cycle shows that all the animals absorb carbon dioxide directly from atmosphere or from the plants.
How can we survive without oxygen?
Life is not possible without oxygen. About 20% of air is oxygen. All the living beings on earth need oxygen for respiration. Oxygen is essential for burning. You will think that the constant use of oxygen from the atmosphere will bring its end some day. Bu tin nature the oxygen cycle is constantly going on and no disturbance has occurred to the balance of this gas. This cycle like nitrogen cycle is a continuous one. Green plants absorb carbon dioxide gas form the atmosphere of photosynthesis. In the daytime, all the trees and plants give out oxygen and take in carbon dioxide. At night, they give out carbon dioxide. This way, the quantity of oxygen in the atmosphere remains stable.
What is the use of nitrogen in soil?
It is utilized by plants or animals in the form of several compounds like ammonia or amino acids. Many bacteria of soil like Azotobacter and clostridium convert the atmospheric nitrogen into nitrogenous compounds which can be absorbed by the plants.
How do plants absorb nitrates?
Plants absorb nitrate salts through their roots and synthesize proteins in their cells. Nitrogen enters into the body of animals when they eat these plants. Bacteria and fungi decompose the dead bodies on earth. Nitrosomonas bacteria convert ammonia into nitrites and nitrobacteria convert nitrites into nitrates.
Why is water important for plants?
The hydrosphere gets its most abundant element, the hydrogen, from water only. Water is formed by the combination of oxygen and hydrogen . During photo synthesis hydrogen is produced by the dissociation of water which forms glucose after combing with carbon dioxide. Plants provide food for herbivores and these animals get glucose and proteins from plants only. Hydrogen forms carbohydrates which is an important source of energy for living being. We take these carbohydrates in the form of food. These help our life cycle to continue.
What are the elements in the hydrogen cycle?
Innumerable kinds of plants and animals are found on earth which is different from each other in shape, size and structure. All these are basically made up of carbon, nitrogen, oxygen and hydrogen. Animals get these elements from nature only.
How do plants absorb water?
Instead of taking in oxygen and breathing out carbon dioxide like animals do,plants take in carbon dioxide from the atmosphere. Plants absorb water from the ground up through their roots. During photosynthesis, the energy from the sun splits the water molecules into hydrogen and oxygen.
What would happen if plants stopped taking up CO2?
In the event that plants cease to take up CO2 all together, they will cease to convert sunlight into carbohydrates, and die. The death of autotrophs would lead to a chain reaction of the death of all higher order organisms. Mankind could survive on food stuffs on hand, but only for a very short time. It has been said that any western society, its members are just 3 meals away from revolution.
What is the process of respiration?
All plants and animals on earth engage in a process called respiration. Respiration combines oxygen and the food created during photosynthesis to produce usable energy. One of the byproducts of respiration is CO2, this is the opposite of photosynthesis. It is not unusual for plants to stop taking in carbon dioxide to uptake small amounts of oxygen at night.
Where does nitrogen come from?
Nitrogen usually comes from nitrates in the soil. Some plants are able to get it directly from air, it is very advantageous since air is composed of nearly 80% of nitrogen. Nitrogen is essential to get amino acid which will compose proteins.
Do plants emit oxygen?
Do you know plant does not only emit oxygen but also uses them when they get no sunlight for photosynthesis.
Does photosynthesis use oxygen?
According to here: http://en.wikipedia.org/wiki/Photosynthesis, photosynthesis generates oxygen, it doesn't use it. Conceivably a plant could store the oxygen it makes during the day and use it to respire at night like ordinary animals do. The roots need to respire during the day too and even the leaves need, I think, to stay alive during the day partly, by respiring and using sugar molecules previously generated by photos
