Select the odd one w.r.t non endospermic seeds.

Options

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

Answer

To solve the question of selecting the odd one out with respect to non-endospermic seeds, we will follow these steps:

### Step 1: Understand Non-Endospermic Seeds
Non-endospermic seeds, also known as exalbuminous seeds, are those seeds where the food reserve is stored in the cotyledons rather than in the endosperm. This means that the cotyledons are the primary source of nutrition for the developing plant.

### Step 2: Identify Examples of Non-Endospermic Seeds
Common examples of non-endospermic seeds include:
- Bean
- Pea
- Gram
- Groundnut
- Sagittaria
- Orchids

### Step 3: Analyze the Options Given
We need to evaluate the options provided in the question to determine which one does not fit the category of non-endospermic seeds. The options are:
1. Bean
2. Castor
3. Groundnut
4. Pea

### Step 4: Evaluate Each Option
- **Bean**: This is a non-endospermic seed.
- **Castor**: This is an endospermic seed because the endosperm is located outside the cotyledons, which are small and leafy.
- **Groundnut**: This is a non-endospermic seed.
- **Pea**: This is also a non-endospermic seed.

### Step 5: Identify the Odd One Out
From the evaluation:
- The bean, groundnut, and pea are all non-endospermic seeds.
- The castor is the only endospermic seed among the options.

### Conclusion
The odd one out with respect to non-endospermic seeds is **Castor** (Option 2).
