Non albuminous seeds are present in :-

Options

A. Maize
B. Wheat
C. Rice
D. Vallisneria

Answer

To determine which of the given options contains non-albuminous seeds, we need to understand the difference between albuminous and non-albuminous seeds.

1. **Identify Seed Types**:
- **Albuminous Seeds**: These seeds contain endosperm, which is the tissue that provides nourishment to the developing plant embryo. Examples include maize, wheat, and rice.
- **Non-albuminous Seeds (Exalbuminous)**: These seeds store their food primarily in the cotyledons rather than in the endosperm. Examples include gram, pea, bean, and groundnut.

2. **Analyze the Options**:
- **Maize**: This is an albuminous seed because it stores food in the endosperm.
- **Wheat**: This is also an albuminous seed for the same reason.
- **Rice**: Like maize and wheat, rice is an albuminous seed.
- **Valisneria**: This is a freshwater aquatic plant that is known to have non-albuminous seeds.

3. **Conclusion**:
- Based on the analysis, the only option that contains non-albuminous seeds is **Valisneria**.

Thus, the correct answer is **Valisneria**.
