The branching where main stem grows endlessly due to presence of a terminal bud, is

Options

A. cymose uniparous
B. racemose
C. helicoid cyme
D. scorpioid cyme

Answer

To answer the question regarding the type of branching where the main stem grows endlessly due to the presence of a terminal bud, we can break down the concepts involved:

### Step-by-Step Solution:

1. **Understanding Terminal Buds**:
- The terminal bud is located at the tip of the stem and is responsible for the upward growth of the plant. It contains meristematic tissue, which allows for continuous growth.

2. **Types of Branching**:
- There are various types of branching patterns in plants, including:
- **Cymos**: Determinate growth where the main axis ends in a flower, limiting further growth.
- **Rhizomos**: A type of inflorescence where the main axis continues to grow indefinitely without terminating in a flower.
- **Helicoid Chyme**: Determinate inflorescence where flowers develop on one side of the axis, causing curvature.
- **Scorpioid Chyme**: Curved axis with flowers alternating on either side.

3. **Identifying the Correct Type**:
- The question specifically asks for the type of branching where the main stem grows endlessly due to the terminal bud.
- Among the options provided, **Rhizomos** is the correct answer because it allows for indefinite growth of the main stem without terminating in a flower.

4. **Conclusion**:
- Therefore, the branching where the main stem grows endlessly due to the presence of a terminal bud is referred to as **Rhizomos**.

### Final Answer:
The correct answer is **Rhizomos**.
