An endospermic seed is

Options

A. Pea
B. Gram
C. Castor
D. Bean.

Answer

### Step-by-Step Solution:

1. **Definition of Endospermic Seed**: An endospermic seed is a type of seed that contains endosperm, which is a tissue that provides nourishment to the developing embryo.

2. **Formation of Seeds**: Seeds are the result of fertilization in angiosperms (flowering plants). After fertilization, the ovule develops into a seed, and the ovary develops into a fruit.

3. **Stored Food Material**: In endospermic seeds, the food reserves are stored in the form of endosperm in addition to the cotyledons. Cotyledons are the first leaves that appear on the seedling and can also store food.

4. **Examples of Endospermic Seeds**: Common examples of endospermic seeds include castor and coconut. These seeds retain their endosperm, which is utilized during the germination process.

5. **Comparison with Non-Endospermic Seeds**: In contrast, non-endospermic seeds (also known as exalbuminous seeds) do not contain endosperm. Examples include seeds from the legume family, such as pea, gram, and bean.

6. **Conclusion**: Therefore, an endospermic seed is characterized by the presence of endosperm, which serves as a food source during germination.
