Transport of auxins is

Options

A. diffuse
B. always acropetal
C. polar
D. non polar

Answer

**Step-by-Step Solution:**

1. **Understanding Auxins**: Auxins are a class of plant hormones that play a crucial role in regulating plant growth and development. They influence various processes such as cell elongation, root formation, and fruit development.

2. **Transport Mechanism**: The transport of auxins within the plant is not random; it follows a specific pattern. This transport is essential for the proper functioning of auxins in directing plant growth.

3. **Types of Transport**: The question presents four options regarding the transport of auxins: diffuse, always acrobatical, polar, and non-polar.

4. **Analyzing the Options**:
- **Diffuse**: This implies a passive movement that is not regulated, which is not the case for auxins.
- **Always Acrobatical**: This term does not accurately describe the transport mechanism of auxins.
- **Polar**: This indicates that the transport is directional and regulated, which is true for auxins. They move from the shoot towards the root in a specific manner.
- **Non-Polar**: This would suggest a lack of directionality, which is incorrect for auxin transport.

5. **Conclusion**: The correct answer is "polar" transport. This means that auxins are transported in a regulated and directional manner, which is essential for coordinating plant growth and responding to environmental changes.

**Final Answer**: The transport of auxins is **polar**.
