In Opuntia, stem is flat, leaf like and photosynthetic

Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Understanding the Plant Structure**: - Opuntia, commonly known as prickly pear, is a type of cactus. Its stem is modified to be flat and leaf-like. 2. **Adaptation to Environment**: - Opuntia thrives in arid or desert conditions where water is scarce. The flat, leaf-like structure of the stem helps the plant adapt to these dry environments. ...
