Very hard endosperm is produced in

Options

A. Areca
B. Phytelepas
C. Phoenix
D. All the above.

Answer

To solve the question "Very hard endosperm is produced in," we will analyze the options provided: Eryca, Fetalepas, Funix, or all of the above.

### Step-by-Step Solution:

1. **Understanding Endosperm**:
- Endosperm is a tissue produced in the seeds of flowering plants and provides nutrition to the developing embryo. It can be classified into different types based on its texture and composition.

2. **Identifying Types of Endosperm**:
- There are two main types of endosperm:
- **Liquid Endosperm**: This is the initial form of endosperm that is often liquid in consistency.
- **Hard Endosperm**: This is the mature form of endosperm that is dense and hard, providing structural support and nutrition.

3. **Analyzing the Options**:
- **Eryca**: This plant produces liquid endosperm initially, which matures into hard endosperm.
- **Fetalepas**: Similar to Eryca, it starts with liquid endosperm that converts to hard endosperm upon maturation.
- **Funix**: This plant also follows the same pattern of developing from liquid to hard endosperm.

4. **Conclusion**:
- Since all three plants (Eryca, Fetalepas, and Funix) produce very hard endosperm upon maturation, the correct answer to the question is **"all of the above."**

### Final Answer:
**All of the above** (Eryca, Fetalepas, Funix).
