Non endospermic seeds are present in :-

Options

A. Castor
B. Pea
C. Maize
D. Wheat

Answer

To determine which of the given options contains non-endospermic seeds, we need to understand the concept of endosperm and the types of seeds.

### Step-by-Step Solution:

1. **Understanding Endosperm:**
- Endosperm is a tissue that provides nutrition to the developing embryo in seeds. It is formed as a result of double fertilization, where one sperm cell fuses with the egg cell to form the zygote, and another sperm cell fuses with two polar nuclei to form the triploid endosperm (3N).

2. **Types of Seeds:**
- **Endospermic Seeds (Albuminous Seeds):** These seeds retain some endosperm even after germination. Examples include most monocots (like maize and wheat) and some dicots (like castor).
- **Non-Endospermic Seeds (Exalbuminous Seeds):** These seeds do not have any endosperm left at maturity. Instead, the nutrients are stored in the cotyledons. Most dicots fall into this category. An example is the pea.

3. **Analyzing the Options:**
- **Castor:** This is an example of an endospermic seed.
- **Pea:** This is an example of a non-endospermic seed.
- **Maize:** This is an example of an endospermic seed.
- **Wheat:** This is also an example of an endospermic seed.

4. **Conclusion:**
- The only option that represents non-endospermic seeds is **Pea**.

### Final Answer:
Non-endospermic seeds are present in **Pea**.
