NEET BIOLOGY

Detailed explanation-1: -Stomata are surrounded by two guard cells that change shape in response to environmental factors and open or close the stoma. Which of the following best explains how the structure of the leaf is used in processes that occur in plants? Gases for photosynthesis are exchanged through the surface of the leaf.

Detailed explanation-2: -Stomata, as mentioned above, are the structures through which gas exchange occurs in leaves. Each stoma is surrounded by two guard cells, which can open and close depending on environmental conditions.

Detailed explanation-3: -Leaves are adapted for photosynthesis and gaseous exchange. They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out.

Detailed explanation-4: -Stomata are small pores present on the lower surface of green leaves of plants. They are responsible for the exchange of oxygen and carbon dioxide. Excess water is also removed from the plant through the stomata.

Detailed explanation-5: -Structure of a leaf The cuticle helps retain water inside the leaf cells. The epidermis houses the guard cells which regulate the movement of water into and outside the cell. Guard cells do so by controlling the size of the pores also called stomata. Mesophyll: This forms the middle layer of the leaf.
