Endosperm is completely consumed by the developing embryo in

Options

A. Coconut
B. Pea
C. Maize
D. Castor

Answer

To determine which plant's endosperm is completely consumed by the developing embryo, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Role of Endosperm**:
- The endosperm is a tissue that provides nourishment to the developing embryo in seeds. It is formed from the fusion of one male gamete with the two polar nuclei in the embryo sac, resulting in a triploid structure.

2. **Identify Types of Seeds**:
- Seeds can be classified into two categories based on the presence of endosperm:
- **Endospermic seeds (albuminous seeds)**: These seeds retain their endosperm when the embryo develops. Examples include maize, castor, and coconut.
- **Non-endospermic seeds (exalbuminous seeds)**: These seeds completely consume their endosperm during embryo development. Examples include pea, beans, and groundnut.

3. **Analyze the Options**:
- The options provided are coconut, pea, maize, and castor.
- **Coconut**: Has liquid endosperm; it is endospermic.
- **Pea**: The endosperm is completely consumed by the developing embryo; it is non-endospermic.
- **Maize**: Retains endosperm; it is endospermic.
- **Castor**: Retains endosperm; it is endospermic.

4. **Conclusion**:
- The only option where the endosperm is completely consumed by the developing embryo is **pea**.

### Final Answer:
The endosperm is completely consumed by the developing embryo in **pea**.
