Castor is a .........seed .

Options

A. Monocot and endospermic
B. Dicot and albuminous
C. Dicot and perispermic
D. Monocot and Albuminous

Answer

To solve the question "Castor is a .........seed," we need to identify the correct classification of the castor seed from the provided options.

### Step-by-Step Solution:

1. **Understanding Seed Types**:
- Seeds can be classified based on how they store food.
- There are two main types:
- **Endospermic (Albuminous) Seeds**: These seeds store food in the endosperm, which remains in the seed after the embryo absorbs what it needs.
- **Non-Endospermic (Exalbuminous) Seeds**: These seeds store food in the cotyledons, and the endosperm is completely used up by the embryo.

2. **Identifying Castor Seed**:
- Castor seeds are known to store their food in the form of endosperm, which makes them **endospermic (albuminous)** seeds.
- This means that even after the embryo has absorbed some food, some endosperm remains.

3. **Classification of Castor Seed**:
- Castor is also classified as a **dicot** seed, which means it has two cotyledons. However, in the case of castor, the cotyledons are thin and do not store significant food reserves.

4. **Evaluating Options**:
- **Option 1**: Monocot and endospermic seed - Incorrect (Castor is a dicot).
- **Option 2**: Dicot and albuminous - Correct (Castor is a dicot seed with food stored in endosperm).
- **Option 3**: Dicot and perispermic - Incorrect (Castor does not have perisperm).
- **Option 4**: Monocot and albuminous - Incorrect (Castor is a dicot).

5. **Conclusion**:
- The correct answer is **Option 2: Dicot and albuminous**.

### Final Answer:
Castor is a **dicot and albuminous seed**.
