Find the correct answers : Seeds have separate endosperm
(a) Maize (b) Onion (c) Rice (d) Bean

Answer

To solve the question regarding which seeds have separate endosperm, we will analyze each option one by one.

### Step-by-Step Solution:

1. **Understanding Endosperm**:
- Endosperm is a tissue that provides nutrition to the developing embryo in seeds. Seeds can be classified based on whether they have a separate endosperm or if the endosperm is absorbed by the cotyledons.

2. **Analyzing Each Option**:
- **(a) Maize**: Maize seeds are classified as endospermic (or albuminous) seeds because they have a well-developed endosperm that remains separate from the cotyledons.
- **(b) Onion**: Onion seeds also have a separate endosperm, making them endospermic seeds.
- **(c) Rice**: Rice seeds are similar to maize and onion in that they have a separate endosperm, thus they are also classified as endospermic seeds.
- **(d) Bean**: Bean seeds are classified as non-endospermic seeds because the food reserves are stored in the cotyledons, and the endosperm is not present as a separate structure.

3. **Conclusion**:
- Based on the analysis, the seeds that have a separate endosperm are Maize (a), Onion (b), and Rice (c). The Bean (d) does not have a separate endosperm.

### Final Answer:
The correct answers are (a) Maize, (b) Onion, and (c) Rice.
