In situ germplasm conservation is done by

Options

A. Biosphere reserves
B. Germplasm banks
C. Pollen banks
D. Botanical gardens

Answer

**Step-by-Step Solution:**

1. **Understanding In-situ Conservation:**
- In-situ conservation refers to the preservation of biological diversity in its natural habitat. This means that species are conserved in the environment where they naturally occur, rather than being removed from their habitat.

2. **Identifying Examples of In-situ Conservation:**
- Examples of in-situ conservation include national parks, wildlife sanctuaries, and biosphere reserves. These areas are designated to protect the natural ecosystems and the species that inhabit them.

3. **Differentiating Between In-situ and Ex-situ Conservation:**
- Ex-situ conservation involves the preservation of species outside their natural habitats. This includes methods like germplasm banks, pollen banks, and botanical gardens, where genetic material is stored and maintained away from the original habitat.

4. **Analyzing the Options Given:**
- The options provided in the question are:
- Biosphere reserves
- Germplasm banks
- Pollen banks
- Botanical gardens
- Among these, biosphere reserves are specifically designed for in-situ conservation, while the other three options (germplasm banks, pollen banks, and botanical gardens) are forms of ex-situ conservation.

5. **Conclusion:**
- Therefore, the correct answer to the question "In situ germplasm conservation is done by" is **biosphere reserves**.
