A cell from leaf is made to grow into complete plant under culture conditions. It shows cellular

Options

A. Cloning
B. Totipotency
C. Hybridisation
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question describes a scenario where a cell from a leaf is cultured to grow into a complete plant. We need to identify the biological process that allows this to happen.

2. **Identifying Key Terms**: The options given are:
- A) Cloning
- B) Totipotency
- C) Hybridization
- D) All of the above

3. **Defining Totipotency**: Totipotency refers to the ability of a single cell to divide and develop into a complete organism. In plants, this means that a single cell can give rise to all the different cell types needed to form a whole plant.

4. **Explaining the Process**:
- When a leaf cell is cultured, it can form an undifferentiated mass of cells known as callus.
- The growth hormone auxin is used to promote root formation.
- Cytokinins are then applied to stimulate cell division and differentiation, leading to the formation of various plant structures including stems and leaves.

5. **Conclusion**: Since the process described involves a single leaf cell growing into a complete plant, it exemplifies the concept of totipotency. Therefore, the correct answer is **B) Totipotency**.
