• A. True
• B. False

Answer 1

The correct option is A True

Photosynthesis:

1. Photosynthesis is the process of conversion of light energy (sunlight) into chemical energy (food) by using carbon dioxide, water and chlorophyll, where oxygen is evolved as a by-product.
2. It takes place in the leaves of the plant.
3. Cactus plants are xerophytes that are found mainly in the desert region.
4. To reduce the loss of water from transpiration, leaves get modified to spines (stem).
5. Therefore, the function of leaves like transpiration, respiration and photosynthesis is taken over by green stems.

Final answer :The given statement is true.
