The term 'totipotency' refers to the capacity of a

Options

A. cell to generate whole plant
B. bud to generate whole plant
C. seed to germinate
D. cell to enlarge in size

Answer

**Step-by-Step Solution:**

1. **Understanding the Term 'Totipotency':**
- Totipotency is a biological term that describes the ability of a single cell to divide and produce all the differentiated cells in an organism, including the extra-embryonic tissues.

2. **Context of Plant Tissue Culture:**
- In the context of plant tissue culture, totipotency refers to the ability of plant cells to regenerate into a complete plant. This means that any cell from a plant can potentially develop into a whole new plant under the right conditions.

3. **Definition of Plant Tissue Culture:**
- Plant tissue culture is the technique of growing plant tissues, organs, or cells in a controlled environment, typically in a sterile medium. The part of the plant that is cultured is referred to as the 'explant'.

4. **Key Characteristics of Totipotent Cells:**
- Totipotent cells can give rise to all types of cells in an organism, including the ability to form a complete plant from a single cell.

5. **Identifying the Correct Option:**
- From the options provided, the correct definition of totipotency is: "the capacity of cells to generate the whole plant." Other options, such as "seeds to germinate" or "cells to enlarge in size," do not accurately describe totipotency.

6. **Conclusion:**
- Therefore, the term 'totipotency' refers specifically to the capacity of cells to generate the whole plant.

**Final Answer:**
Totipotency refers to the capacity of cells to generate the whole plant.
