Which of the following is/are functions of the stomata present in the leaf?
Absorbing carbon dioxide from the atmosphere
Giving out oxygen into the atmosphere
Transpiration of excess water
A plant takes in carbon dioxide essential for photosynthesis through the stomata. Stomata expels out the oxygen produced during photosynthesis. They also release water that is absorbed by the roots in the form of water vapour. And this process is called transpiration. The sunlight is absorbed by the chlorophyll that is present in the leaf.
