A plant has weak stem which can coil around an upright support . It is a
(a) Liana
(b) Twiner
(c) Climber
(d) Creeper

Options

A. Liana
B. Twiner
C. Climber
D. Creeper

Answer

To solve the question, we need to identify the type of plant based on the description provided: a plant with a weak stem that can coil around an upright support. Let's analyze each option step by step.

### Step 1: Analyze the Options
1. **Liana**: Lianas are typically woody vines that can grow high into the canopy of forests. They are not specifically characterized by coiling around supports but rather climbing using other means. Therefore, this option is not correct.

2. **Twiner**: Twiners are plants with weak stems that can coil around supports. They use their stems to wrap around upright structures, which fits the description given in the question. An example of a twiner is the morning glory. This option seems to be a strong candidate.

3. **Climber**: Climbers also have weak stems but they usually require additional support structures like tendrils or other means to help them ascend. While they can coil, they are not primarily defined by this ability. This option is less likely to be correct.

4. **Creeper**: Creepers are plants that grow along the ground and do not have the ability to coil around upright supports. They spread horizontally rather than vertically. Therefore, this option is not correct.

### Step 2: Conclusion
Based on the analysis of each option, the plant described in the question is best classified as a **Twiner** (Option B), as it has a weak stem that can coil around an upright support.

### Final Answer:
**(b) Twiner**
