Introduction to how Plants Obtain Carbon Dioxide from Atmosphere
All living organisms require energy in order to conduct life processes and so do plants. For the purpose of performing various metabolic activities plants require food for energy. With the help of the photosynthesis process, plants prepare their own food. Plants need food that can supply energy for their different metabolic activities. The fact is plants cannot move from one place to another in search of food like animals. They stand still and prepare their own food.

Process Of How Plants Obtain Carbon Dioxide from Atmosphere
The process from which plants obtain carbon dioxide (Co2) is called photosynthesis. The green plants are autotrophic, meaning that they synthesize their own food by the process of photosynthesis. In the presence of chlorophyll plants utilize the energy in sunlight to prepare food from water and carbon dioxide. Plants or leaves are green because of the chlorophyll present in the chloroplasts of the plants cells.
Thus, the process by which green plants make their own food like water by using water and sunlight energy and glucose from carbon dioxide in the presence of chlorophyll is known as photosynthesis. This process occurs in the leaves of the leaves of the plant.
Understanding How Plants Obtain Carbon Dioxide
On the surface of leaves of the plants there are a huge number of tiny pores that are called stomata or stoma. For the process of photosynthesis, green plants take CO2 from the air. The carbon dioxide enters the leaves through the stomata present on their surface. Each stomata pore is encompassed by a pair of guard cells. The opening and closing of the stomatal pores is regulated by the guard cells only. When water flows through the guard cells, they expand, become curved and induce the pore to open. Whereas, the guard cells suffer loss of water; they contract, get straight and close the stomatal pore. A huge amount of water is also lost from the cells of the plant leaves vy open stomatal pores. Therefore, when the plant does not require carbon dioxide and seeks to conserve water, the stomatal pores are closed.
What Happens During Photosynthesis?
During the process of photosynthesis, the oxygen gas produced goes out through the leaves of the plants of stomatal pores. Remember that the stomata are also present in the green stems or shoots of a plant. Thus, we can say that the green stems or shoots also display photosynthesis. In most wide-leaved plants, the stomata takes place only in the lower surface of the leaf; however in narrow-leaved plants, the stomata are equally spread on both the sides of the leaf. In aquatic plants or water-borne plants, they use carbon dioxide gas dissolved in water for performing photosynthesis.
Thus, we can say that a stomata pore enables the movement of gases in and out of plant cells. So, the gaseous exchange in plants occurs through the stomata in leaves and other green parts.
The Story Behind Carbon
Plants or green leaves absorb CO2 through tiny openings called stomata that are present on the surface of the leaf. If we take a closer look at a plant leaf, so close that we are able to see the cells, we will find small openings called stomata. Stomata are holes made from spaces between unique cells. These holes are where plants absorb CO2 from the air in the atmosphere.
Once on the inside of the leaf, the CO2 can enter plant cells. Inside the plant cells are unique cell parts known as chloroplasts, where photosynthesis occurs.
Why do Plants have Green Color
One of hundreds of chloroplasts lives inside the plant cell. Plant cells look green because of the molecules in the chloroplasts which reflect green light. Every green plant cell consists of many, many chloroplasts. Most of the rest of the cell generally looks clear. In the chloroplasts, carbon, oxygen, hydrogen, and energy are significantly utilized to make a sugar known as glucose. The whole process of producing glucose is known as photosynthesis. The molecules of glucose combine together to form cellulose. Next, glucose molecules join to form long chains known as cellulose. Cellulose is then used to construct plant structures, like cell walls.
FAQs on Plants Obtain Carbon Dioxide from Atmosphere
1. What are the raw materials required for photosynthesis?
The raw materials needed for photosynthesis are:-
Carbon dioxide (CO2)
Water (H2O)
So what do you think are plants made of? Are they made of air, water or carbon dioxide? Air is largely made of oxygen, nitrogen, and carbon dioxide. Plants absorb carbon dioxide from the air. This carbon makes up most of the building substances that plants use to build new roots, stems or leaves. The oxygen used to produce glucose molecules is also from carbon dioxide.
Water is another essential material plants require to grow, and they get it by absorbing it through their roots. Water contains two hydrogen atoms and one oxygen atom. The hydrogen in water is used in building glucose molecules.
A plant can contain up to 95% water. Think of the water as the filler that’s used between carbon structures. If we eliminate the water from a plant though, and look at just the dry substance, a huge majority of that substance comes from thin air.
Plants also require particles of vitamins and minerals to grow appropriately, which they get through their roots.
Plants require a good amount of energy to nourish their cells and to build new ones so they can grow. Plants also obtain their energy from the sun.
Thus, water + air + sunlight energy = plant growth
2. What is the story behind Air in the atmosphere?
The molecule carbon dioxide is composed of one carbon atom and two oxygen atoms. The air in the atmosphere may seem empty, but it's not. Amazingly, Air is made of tiny bits that are known as molecules. If you have had sufficient air molecules, you could actually even weigh them.
Two of the molecules present in air are oxygen (O2) and carbon dioxide (CO2). You may think that oxygen is the most essential molecule—we need it for living. However, the fact is carbon is equally important. All living things on our planet Earth are made of carbon.
If you eliminated the water from our bodies, you would discover that carbon makes up most of the rest of our weight, or mass. The same remains true for plants.
We humans obtain carbon from our food, but where and how do you think plants get carbon? Plants don't get carbon from any of sources like soil, sun and water but pull carbon out of the air.
