Where are auxins present in the plants ?

Answer

**Step-by-Step Solution:**

1. **Understanding Auxins**: Auxins are plant growth hormones that play a crucial role in various growth and developmental processes in plants. They are also referred to as phytohormones.

2. **Functions of Auxins**: Auxins are involved in several key functions such as:
- Stem elongation
- Apical dominance (the phenomenon where the main central stem of the plant grows more strongly than the other side stems)
- Root initiation (the process of forming new roots)
- Fruit development

3. **Location of Auxins**: Auxins are primarily found at specific locations within the plant. They are concentrated at:
- The tip of the root (root tip)
- The tip of the shoot (shoot tip)

4. **Conclusion**: Therefore, the presence of auxins in plants is specifically at the root tip and the shoot tip, where they facilitate growth and development.

**Final Answer**: Auxins are present at the tip of the root and at the tip of the shoot in plants.
