Tissue culture technique can produce infinite number of new plants from a small parental tissue. The economic importance of the technique is in raising:

Question

Accepted Answer

B. 1. **Background**: tissue culture (also called micropropagation) relies on the property of **totipotency** — the ability of a single plant cell to develop into a complete new plant.

2. Because the new plants are grown vegetatively (without sexual reproduction) from cells of the same parent, all the resulting plants — collectively called a **clone** — are **genetically identical to the parent plant**.

3. This genetically uniform reproduction is exactly what gives the technique its major economic value: farmers and industries can mass-produce plants that are guaranteed to have the same desirable traits as the original parent.

4. This process does **not** aim to create new species, introduce variants (somaclonal variation is usually an unwanted side effect, not the goal), or specifically produce homozygous diploid plants.

5. Hence, the correct answer is **B: genetically uniform population identical to the original parent**.
