Read the following statements and select the correct option:-
A. Gymnosperm does not show xerophytic character.
B. In Cycas , coralloid roots are associated with fungi.
C. All gymnosperms are heterosporous.
D. In conifers , needle - like leaves reduce the surface area.
How many above statement are correct ?

Options

A. A, B and C
B. B, C and D
C. C and D
D. A and D

Answer

To solve the question, we need to analyze each of the statements provided regarding gymnosperms and determine their correctness.

### Step-by-Step Solution:

1. **Statement A: Gymnosperm does not show xerophytic character.**
- **Analysis**: This statement is incorrect. Gymnosperms are known to exhibit xerophytic characteristics, such as having thick bark, sunken stomata, and needle-like leaves, which help them conserve water in dry conditions.
- **Conclusion**: **Incorrect**

2. **Statement B: In Cycas, coralloid roots are associated with fungi.**
- **Analysis**: This statement is also incorrect. Coralloid roots in Cycas are primarily associated with blue-green algae (cyanobacteria), not fungi. They help in nitrogen fixation.
- **Conclusion**: **Incorrect**

3. **Statement C: All gymnosperms are heterosporous.**
- **Analysis**: This statement is correct. Gymnosperms produce two types of spores: microspores (male) and megaspores (female), thus they are heterosporous.
- **Conclusion**: **Correct**

4. **Statement D: In conifers, needle-like leaves reduce the surface area.**
- **Analysis**: This statement is correct. The needle-like leaves of conifers indeed reduce the surface area, which minimizes water loss and helps the plant survive in harsh environments.
- **Conclusion**: **Correct**

### Summary of Correctness:
- Statement A: Incorrect
- Statement B: Incorrect
- Statement C: Correct
- Statement D: Correct

### Final Count of Correct Statements:
Out of the four statements, **2 statements (C and D) are correct**.

### Answer:
**2 statements are correct.**
