Best material for studying mitosis in laboratory is

Options

A. (a) leaf tip
B. (b) shoot tip
C. (c) root tip
D. (d) gamete

Explanation

To determine the best material for studying mitosis in a laboratory, we need to consider which part of a plant contains actively dividing cells. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- A) Leaf tip
- B) Shoot tip
- C) Root tip
- D) Gamete

2. **Understand Mitosis**: Mitosis is the process of cell division where one cell divides to produce two identical daughter cells. To study mitosis, we need tissues where cells are actively dividing.

3. **Examine Each Option**:
- **Leaf tip**: While leaves grow, they do not have the same level of active cell division as root tips or shoot tips.
- **Shoot tip**: Similar to leaf tips, shoot tips do have some meristematic activity, but they are not the best option for observing mitosis.
- **Root tip**: This is a region of active growth in plants, specifically containing the root apical meristem, where cells are continuously dividing.
- **Gamete**: Gametes are specialized cells for reproduction and do not undergo mitosis.

4. **Conclusion**: The root tip contains the root apical meristem, where cells are actively dividing through mitosis. This allows for the observation of various stages of mitosis clearly.

5. **Final Answer**: Therefore, the best material for studying mitosis in a laboratory is **C) Root tip**.
