In Opuntia, the leaves of areoles are modified into

Options

A. spines
B. Glochidia
C. Scales
D. Tendrils.

Answer

**Step-by-Step Solution:**

1. **Understanding the Plant:**
- Opuntia is the scientific name for a type of cactus. Cacti are known for their adaptations to survive in arid environments, such as deserts.

2. **Function of Leaves:**
- The primary function of leaves in most plants is to perform photosynthesis, which is essential for producing food and energy.

3. **Adverse Conditions:**
- In environments with adverse conditions like drought or extreme temperatures, plants may undergo modifications to survive.

4. **Xerophytic Adaptations:**
- Opuntia is classified as a xerophytic plant, meaning it is adapted to survive in dry conditions where water is scarce.

5. **Modification of Leaves:**
- In response to the harsh desert conditions, the leaves of Opuntia are modified into spines. This modification helps reduce the surface area of the leaves, minimizing water loss through transpiration.

6. **Identifying the Correct Option:**
- Among the options provided (spines, glaucedia, scales, tendrils), spines are the correct answer as they are the result of leaf modification in Opuntia.

7. **Conclusion:**
- Therefore, in Opuntia, the leaves of areoles are modified into spines to help the plant conserve water in its desert habitat.

**Final Answer:**
In Opuntia, the leaves of areoles are modified into spines.
