Which type of growth is found in pollen tube:-

Options

A. Lateral growth
B. Apical growth
C. Middle growth
D. No growth

Answer

To determine the type of growth found in the pollen tube, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pollen Tube Formation**:
- Pollen grains, when mature, develop a structure known as the pollen tube. This tube is essential for the fertilization process in flowering plants.

2. **Identifying Growth Types**:
- There are different types of growth in plants, including:
- Lateral Growth: Growth that occurs from the sides.
- Apical Growth: Growth that occurs at the tips (apices) of roots and shoots.
- Middle Growth: Growth that occurs from the middle of a structure.
- No Growth: A state where there is no increase in size.

3. **Analyzing the Pollen Tube**:
- The pollen tube specifically grows from the tip, which is indicative of apical growth. This means that the pollen tube elongates as it grows towards the ovule for fertilization.

4. **Eliminating Incorrect Options**:
- Lateral growth would imply growth from the sides, which does not occur in the pollen tube.
- Middle growth would suggest that the growth starts from the middle of the structure, which is also not applicable here.
- No growth indicates no increase in size, which is incorrect for the pollen tube as it actively grows.

5. **Conclusion**:
- Since the pollen tube grows from the tip, the correct type of growth found in the pollen tube is **apical growth**.

### Final Answer:
The type of growth found in the pollen tube is **apical growth**.
