Micropropagation is

Options

A. propagation of microbes in vitro
B. propagation of plants in vitro
C. propagation of cells in vitro
D. growing plants on smaller scale.

Explanation

### Step-by-Step Text Solution for the Question "Micropropagation is":

1. **Definition of Micropropagation**: Micropropagation is the process of propagating (multiplying) plants in vitro, which means in a controlled environment, typically in a laboratory setting.

2. **Purpose of Micropropagation**: The main aim of micropropagation is to rapidly multiply a stock plant material to produce a large number of progeny or offspring plants.

3. **Clones**: The progeny produced through micropropagation are genetically identical to the parent plant and are referred to as clones.

4. **Efficiency**: This technique allows for the production of a large number of plants in a relatively short amount of time and requires less space compared to traditional propagation methods.

5. **Methods Used**: Micropropagation utilizes modern plant tissue culture techniques, where small pieces of plant tissue (explant) are cultured under sterile conditions to grow into whole plants.

6. **Controlled Environment**: The in vitro conditions provide a sterile environment that helps in preventing contamination and allows for better control over growth conditions such as light, temperature, and nutrients.

7. **Conclusion**: Therefore, micropropagation is defined as the propagation of plants in vitro, which enables the rapid and efficient production of large numbers of clones from a single parent plant.
