Photosynthesis takes place in leaves. Leaves contain that allow for the exchange of gases during the process, and also help with the process of .

The correct answer is - stomata, transpiration.

Explanation:

Photosynthesis is the process that uses light to convert CO2 and water to produce sugar and oxygen. The carbon dioxide is taken up by the little holes-like structures present on the spongy layer of the leaves called stomata. These structures are used for gaseous exchange, taken up oxygen, and releasing oxygen.

Stomata also help in releasing water vapors from the aerial parts during the process of transpiration to prevent the plants to burn in a dry environment and wind.
