Question

In Cactus, photosynthesis is carried out in the __.

Answer 1

Typically, the leaves of the plant play the greatest role in photosynthesis. However, in cacti, the leaves are modified into needles in order to reduce the surface area of transpiration and thus reduce the loss of water. These needles are a characteristic for protection and cannot carry out photosynthesis due to a little surface area. Therefore, it is the stem that performs the process of photosynthesis in these plants.
