Detailed explanation-1: -Its prime function is to exchange the gases by closing and opening the pores in the leaves. It assists in eradicating excess water from the leaves. It removes oxygen and takes in carbon dioxide at the time of photosynthesis.
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. Thousands of them dot on the surface of the plants.
Detailed explanation-3: -Stomata allow for gas exchange to occur, mainly carbon dioxide to enter the plant to make food molecules such as glucose and for oxygen to be released by the plant. It also allows water vapor to escape the plant via transpiration which is a necessary evil. Plants need to open and close the stomata.
Detailed explanation-4: -Stomata is a tiny opening or pore that is used for gas exchange. They are mostly found on the lower surface of leaves. Air enters the plant through these openings. The main function of the stomata is to let in CO2 from the atmosphere for photosynthesis.
Detailed explanation-5: -The main functions of stomata are: Gaseous exchange-Stomatal opening and closure help in the gaseous exchange between the plant and surrounding. It helps in transpiration and removal of excess water in the form of water vapour. Stomatal closure at night prevents water from escaping through pores.
