Answer

To identify the plants with stem tendrils from the given list, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Stem Tendrils**:
- Stem tendrils are slender, thread-like structures that are modified from axillary buds. They help plants climb by wrapping around supports.

2. **Identify the Plants**:
- We need to analyze each plant in the list to see if they exhibit stem tendrils.

3. **Cucumber**:
- Cucumber belongs to the Cucurbitaceae family and is known for its stem tendrils. It uses these tendrils to climb and support itself.

4. **Grape Vine**:
- The grape vine also has stem tendrils. Similar to cucumber, it uses these tendrils to cling to supports as it grows.

5. **Watermelon**:
- Watermelon, another member of the Cucurbitaceae family, also has stem tendrils that assist in climbing.

6. **Pumpkins**:
- Pumpkins, like cucumber and watermelon, exhibit stem tendrils which help them in their climbing growth habit.

7. **Citrus**:
- Citrus plants do not have stem tendrils. Instead, their axillary buds are modified into thorns for protection against herbivores.

### Conclusion:
The plants from the list that have stem tendrils are:
- I) Cucumber
- II) Grape vine
- III) Watermelon
- IV) Pumpkins

The plant that does not have stem tendrils is:
- V) Citrus

### Final Answer:
- **Plants with Stem Tendrils**: Cucumber, Grape vine, Watermelon, Pumpkins
- **Plant without Stem Tendrils**: Citrus
