Seed of Black Pepper is

Options

A. Endospermic
B. Exalbuminous
C. Acotyledonous
D. Perispermic

Answer

To determine the classification of the seed of black pepper, we need to analyze the definitions and characteristics of the various types of seeds mentioned in the question: endospermic, exalbuminous, cotyledonous, and perispermic.

### Step-by-Step Solution:

1. **Understand Endospermic Seeds**:
- Endospermic seeds are those that have reserve food material stored in the endosperm. This is the tissue that surrounds the embryo and provides nutrients during germination.
- **Hint**: Look for seeds that have their food reserves in the endosperm.

2. **Evaluate Black Pepper for Endospermic Characteristics**:
- In the case of black pepper, it does not have significant reserve food material in the endosperm.
- **Hint**: Check if the seed has food reserves in the endosperm to classify it as endospermic.

3. **Understand Exalbuminous Seeds**:
- Exalbuminous seeds are those where the reserve food material is stored in the cotyledons rather than the endosperm.
- **Hint**: Identify if the cotyledons contain the food reserves.

4. **Evaluate Black Pepper for Exalbuminous Characteristics**:
- The seed of black pepper does not store its food reserves in the cotyledons either.
- **Hint**: Determine if the cotyledons are the main source of food reserves to classify as exalbuminous.

5. **Understand Cotyledonous Seeds**:
- Cotyledonous seeds are those that have one or more cotyledons, which are the first leaves that appear from a germinating seed.
- **Hint**: Check if the seed has cotyledons and their role in food storage.

6. **Evaluate Black Pepper for Cotyledonous Characteristics**:
- Black pepper seeds do not have significant cotyledons, which means they cannot be classified as cotyledonous.
- **Hint**: Look for the presence or absence of cotyledons in the seed.

7. **Understand Perispermic Seeds**:
- Perispermic seeds are those that contain a perisperm, which is a tissue that provides additional food reserves. This tissue is derived from the nucellus.
- **Hint**: Identify if the seed has perisperm as a food reserve.

8. **Evaluate Black Pepper for Perispermic Characteristics**:
- The seed of black pepper does contain perisperm, which makes it a perispermic seed.
- **Hint**: Confirm the presence of perisperm to classify the seed as perispermic.

### Conclusion:
Based on the analysis, the seed of black pepper is classified as a **perispermic seed**. Therefore, the correct answer is option number 4.
