Read the following statements and find out the incorrect statement.

Options

A. Both stem tendrils and thorns are the modification of axillary buds
B. Thorns are woody, curved and pointed structures found in Citrus and Bougainvillea for protecting them from browsing animals
C. Opuntia and Euphorbia are found into arid regions. They contain chlotophyll in their stem and carry out photosynthesis
D. Stem tendrils are found in ground and grapevines that are slender and spirally coiled and help plants to climb.

Explanation

To solve the question of identifying the incorrect statement among the provided options, we will analyze each statement step by step.

### Step-by-Step Solution:

1. **Analyze Statement 1**:
- The statement claims that both stem tendrils and thorns are modifications of axillary buds.
- This is correct because both thorns and tendrils originate from axillary buds.
- **Conclusion**: Statement 1 is correct.

2. **Analyze Statement 2**:
- The statement describes thorns as woody, curved, and pointed structures found in citrus and bougainvillea, serving to protect the plants from browsing animals.
- While thorns are indeed woody and pointed, they are not typically described as curved; they are usually straight.
- The incorrect term here is "curved."
- **Conclusion**: Statement 2 is incorrect due to the use of the word "curved."

3. **Analyze Statement 3**:
- This statement discusses arid regions where plants have chlorophyll in their stems and can perform photosynthesis.
- It correctly mentions that in xerophytic conditions, leaves are modified into spines, and stems become flattened and modified into phylloclades.
- **Conclusion**: Statement 3 is correct.

4. **Analyze Statement 4**:
- The statement states that stem tendrils are found in ground and grapevines, are cylindrical and spherically coiled, and help the plant to climb.
- It correctly identifies tendrils as thin, wiry, leafless, and spirally coiled branches that assist in climbing.
- **Conclusion**: Statement 4 is correct.

### Final Conclusion:
The incorrect statement is **Statement 2**, which incorrectly describes thorns as "curved" instead of "straight."
