An example of a seed with endosperm and perisperm is

Options

A. Coffee
B. Lily
C. Castor
D. Cotton

Answer

To solve the question about an example of a seed with both endosperm and perisperm, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Endosperm**: This is a tissue in the seed that provides nutrition to the developing embryo. It is formed during fertilization and is crucial for the growth of the seedling.
- **Perisperm**: This is a tissue that surrounds the endosperm and also provides additional nutrition to the embryo. It is derived from the nucellus of the ovule.

2. **Identify the Options**:
- The options provided are coffee, lily, and cotton. We need to analyze whether these seeds contain both endosperm and perisperm.

3. **Analyze Each Option**:
- **Coffee**: Coffee seeds contain endosperm, but they do not have a perisperm that is integrated with the endosperm.
- **Lily**: Lily seeds also have endosperm, but they do not have a perisperm.
- **Cotton**: Cotton seeds have endosperm, but again, there is no perisperm present.

4. **Identify the Correct Example**:
- **Castor**: In contrast to the above options, castor seeds have both endosperm and perisperm that are fused together, forming a structure known as a caruncle. This is a unique characteristic of castor seeds.

5. **Conclusion**:
- Therefore, the correct answer to the question is **Castor**, as it is the only example among the options that contains both endosperm and perisperm together.
