How many of the following shows epigeal seed germination?[Cucurbits, Rice, Mustard, Mango, Castor, Gram, Onion, Beans, Groundnut]

Options

A. Seven
B. Six
C. Eight
D. Five

Answer

To determine how many of the listed plants exhibit epigeal seed germination, we need to understand the concept of epigeal germination and identify which of the plants fall under this category.

### Step-by-Step Solution:

1. **Understand Epigeal Germination**:
- Epigeal germination is a type of seed germination where the cotyledons (seed leaves) emerge above the ground. This occurs when the hypocotyl (the stem below the seed leaves) elongates and pushes the cotyledons upward.

2. **List the Plants**:
- The plants mentioned in the question are: Cucurbits, Rice, Mustard, Mango, Castor, Gram, Onion, Beans, and Groundnut.

3. **Identify Epigeal Germination Examples**:
- **Cucurbits**: Exhibit epigeal germination.
- **Rice**: Exhibits hypogeal germination (cotyledons remain below ground).
- **Mustard**: Exhibits epigeal germination.
- **Mango**: Exhibits hypogeal germination.
- **Castor**: Exhibits epigeal germination.
- **Gram**: Exhibits hypogeal germination.
- **Onion**: Exhibits epigeal germination.
- **Beans**: Exhibit epigeal germination.
- **Groundnut**: Exhibits hypogeal germination.

4. **Count the Plants with Epigeal Germination**:
- From the above analysis, the plants that show epigeal germination are:
- Cucurbits
- Mustard
- Castor
- Onion
- Beans
- This gives us a total of **5 plants** that exhibit epigeal germination.

5. **Final Answer**:
- Therefore, the answer to the question is **5**.
