Enlist the applications of tissue culture.

Explanation

**Step-by-Step Text Solution:**

1. **Micropropagation**: This is the first application of tissue culture. Micropropagation refers to the technique of producing multiple plants from a small tissue sample. This method allows for the rapid multiplication of plants, ensuring that many identical copies can be produced in a short time.

2. **Production of Disease-Free Plants**: Tissue culture techniques can be used to produce plants that are free from diseases. By culturing plant tissues in a controlled environment, it is possible to eliminate pathogens and ensure that the resulting plants are healthy and disease-resistant.

3. **Production of Secondary Metabolites**: Tissue culture can also be employed to produce secondary metabolites, which are organic compounds that are not directly involved in the normal growth, development, or reproduction of plants. These metabolites can have significant pharmaceutical and industrial applications.
