Select the option that contains all plants which produce nonendospermic seeds

Options

A. Gram, Pea, Bean, Groundnut
B. Castor, Peanut, Orchid, Wheat
C. Coconut, Walnut, Wheat, Gram
D. Castor, Maize, Coconut, Orchid

Answer

To solve the question of selecting the option that contains all plants which produce non-endospermic seeds, we will follow these steps:

### Step 1: Understand the Types of Seeds
Seeds can be classified into two categories based on the presence or absence of endosperm:
- **Endospermic seeds (albuminous seeds)**: These seeds have endosperm present, which provides nutrition to the developing embryo.
- **Non-endospermic seeds (exalbuminous seeds)**: These seeds do not have endosperm, as the nutrients are stored in the cotyledons.

### Step 2: Analyze the Options
We need to evaluate each plant listed in the options to determine whether they produce non-endospermic seeds.

1. **Gram**: Non-endospermic (exalbuminous)
2. **Pea**: Non-endospermic (exalbuminous)
3. **Bean**: Non-endospermic (exalbuminous)
4. **Groundnut**: Non-endospermic (exalbuminous)
5. **Castor**: Endospermic (albuminous)
6. **Peanut**: Non-endospermic (exalbuminous)
7. **Orchid**: Generally non-endospermic but has perisperm.
8. **Wheat**: Endospermic (albuminous)
9. **Coconut**: Endospermic (albuminous)
10. **Walnut**: Endospermic (albuminous)
11. **Wheat gram**: Non-endospermic (exalbuminous)

### Step 3: Identify the Correct Option
From the analysis, we find that:
- The plants that produce non-endospermic seeds are: Gram, Pea, Bean, Groundnut, and Peanut.
- Castor, Wheat, Coconut, and Walnut are endospermic seeds.

Thus, the correct option that contains all plants which produce non-endospermic seeds is **Gram, Pea, Bean, Groundnut**.

### Final Answer
The correct option is **Gram, Pea, Bean, Groundnut**.
