why desert plants have green stems?
Dear Student
Desert plants like cacti have developed water-saving approach to the process of photosynthesis.
Leaves have reduced leaves to spines to prevent water loss and stem contains chlorophyll to perform photosynthesis. They have green stems that have stomata that open at night and close in the day. Their stem contains chlorophyll.
