A member of the plant family which stores food in the endosperm

Options

A. Graminae
B. Malvaceae
C. Solanaceae
D. Leguminosae

Answer

To solve the question regarding which member of the plant family stores food in the endosperm, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Endosperm**:
- Endosperm is a tissue found in the seeds of flowering plants. It serves as a food reserve for the developing embryo, providing essential nutrients during germination.
- The primary form of stored food in the endosperm is starch, which is a carbohydrate that supplies energy.

2. **Identifying Plant Families**:
- We need to identify which plant families typically store food in the endosperm.
- The two main categories of flowering plants are monocots and dicots.

3. **Monocots vs. Dicots**:
- Monocots (e.g., members of the family Gramineae) usually have seeds that contain a significant amount of endosperm, which provides nutrition to the embryo.
- Dicots (e.g., members of the families Malvaceae, Solanaceae, and Leguminosae) often have little to no endosperm remaining at maturity, as the cotyledons (seed leaves) usually absorb the nutrients.

4. **Analyzing the Options**:
- The options provided include:
- Gramineae (Monocot)
- Malvaceae (Dicot)
- Solanaceae (Dicot)
- Leguminosae (Dicot)
- Among these, Gramineae is the only monocot family listed.

5. **Conclusion**:
- Since Gramineae is a monocot family that stores food in the endosperm, it is the correct answer to the question.

### Final Answer:
**Gramineae** is the member of the plant family which stores food in the endosperm.
