Food is stored in albuminous seed in

Options

A. testa
B. cotyledon
C. endosperm
D. plumule

Answer

To answer the question "Food is stored in albuminous seed in," we need to analyze the options provided:

1. **Testa**: This is the outer seed coat that protects the seed. It does not store food.

2. **Cotyledon**: This part of the seed is responsible for storing food in exalbuminous seeds, where the endosperm is utilized. However, in albuminous seeds, the cotyledons are typically thin and do not store significant food.

3. **Endosperm**: This is the key component in albuminous seeds. The endosperm is the tissue that surrounds the embryo and serves as the primary food storage area. It is rich in nutrients and is the main source of food for the developing plant.

4. **Plumule**: This part of the seed develops into the shoot system of the plant. It does not store food.

Based on this analysis, the correct answer to the question is:

**Food is stored in albuminous seed in the Endosperm.**

### Step-by-Step Solution:
1. Identify the components of the seed: Testa, Cotyledon, Endosperm, and Plumule.
2. Analyze the function of each component:
- Testa: Protective outer layer, no food storage.
- Cotyledon: Stores food in exalbuminous seeds, not significant in albuminous seeds.
- Endosperm: Main food storage tissue in albuminous seeds.
- Plumule: Develops into the shoot system, no food storage.
3. Conclude that the Endosperm is where food is stored in albuminous seeds.
