EVERYDAY SCIENCE

Detailed explanation-1: -Through photosynthesis, they use sunlight and carbon dioxide to make food, belching out the oxygen that we breathe as a byproduct. This evolutionary innovation is so central to plant identity that nearly all land plants use the same pores-called stomata-to take in carbon dioxide and release oxygen.

Detailed explanation-2: -The small pores present on leaves help plants take in carbon dioxide and give out oxygen during the process of photosynthesis. These pores are called stomata.

Detailed explanation-3: -Most plants use a pore-like structure called stomata (singular: stoma) on the undersides of leaves to absorb carbon dioxide from the air. The carbon dioxide is used to build sugars, which can be used by the plant as energy or for incorporation into the plants’ fibrous cell walls.

Detailed explanation-4: -On the underside of leaves and elsewhere, depending on the plant, are tiny openings called stomata-thousands of them per leaf with variations by plant species. Like little castle gates, pairs of cells on the sides of the stomatal pore-known as guard cells-open their central pore to take in the carbon dioxide.

Detailed explanation-5: -After carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into sugars.
