Question

Stomata remain closed in desert plants during day time. How do they do photosynthesis?

Answer 1

Photosynthesis in desert plants:

1. Desert plants photosynthesize by a modified process of photosynthesis called CAM photosynthesis.
   
2. There are less stomata in desert plants as the leaves are modified to form spines and photosynthesis occurs in the green stem.
   
3. The stomata does not open during the day to avoid water loss and only opens during the night for carbon dioxide to enter the plant.
   
4. ​The carbon dioxide is present as an intermediate inside the plant to perform photosynthesis during the day.
