Detailed explanation-1: -Stomata are tiny openings or pores that allow the exchange of gases. They are mostly found on the under-surface of plant leaves.

Detailed explanation-2: -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. Stomata are tiny, microscopic and critical for photosynthesis.

Detailed explanation-3: -Carbon dioxide and oxygen cannot pass through the cuticle, but move in and out of leaves through openings called stomata (stoma = “hole"). Guard cells control the opening and closing of stomata. When stomata are open to allow gases to cross the leaf surface, the plant loses water vapor to the atmosphere.

Detailed explanation-4: -Stomata are tiny pores present on the surface of the leaves of plants. These pores are surrounded by guard cells. The carbon dioxide from the air is taken through these tiny pores to carry out the process called photosynthesis.

Detailed explanation-5: -Stomatal pores are the common sites responsible for taking up carbon dioxide from the atmosphere for photosynthesis as well as releasing oxygen into the atmosphere.
