For plants tissue culture which among the following is required ?

Options

A. Trypsin
B. Kinetin
C. Caffeine
D. Cocumarin

Answer

**Step-by-Step Solution:**

1. **Understanding Plant Tissue Culture**: Plant tissue culture is a technique used to grow plant cells, tissues, or organs in a controlled environment. It requires specific substances to promote growth and development.

2. **Identifying the Options**: The question provides four options:
- A) Trypsin
- B) Kyanating
- C) Kaifin
- D) Kukumarin

3. **Analyzing Each Option**:
- **Trypsin**: This is a proteolytic enzyme that breaks down proteins and is not typically used in plant tissue culture.
- **Kyanating**: This is a phytohormone known to promote cell division and growth in plants.
- **Kaifin**: This is not a recognized substance in the context of plant tissue culture.
- **Kukumarin**: This is also not a known substance related to plant tissue culture.

4. **Selecting the Correct Answer**: Among the options, Kyanating is the only one that is a phytohormone and is important for promoting cytokinin activity, which is crucial for plant tissue culture. Therefore, the correct answer is **B) Kyanating**.

5. **Understanding the Role of Kyanating**: Kyanating promotes cytokinin activity, which is essential for:
- Stimulating cell division (cytokinesis).
- Supporting mitotic division, which is necessary for the growth of plant tissues in culture.

**Final Answer**: The required substance for plant tissue culture is **B) Kyanating**.
