Plant genes of endangered species are stored in :

Options

A. Gene library
B. Gene bank
C. Herbarium
D. None of these

Answer

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

1. **Understanding the Question**: The question asks where plant genes of endangered species are stored. This requires knowledge of methods used for preserving genetic material in plants.

2. **Analyzing the Options**: The options provided include:
- Gene Library
- Gene Bank
- Herbarium

3. **Defining Gene Library**: A gene library is a collection of DNA fragments that represent the genetic material of an organism. It is used for research and does not specifically store genes of endangered species.

4. **Defining Gene Bank**: A gene bank is a type of biorepository that preserves genetic material. For plants, this can involve storing seeds or plant cuttings, often at very low temperatures (e.g., -196 degrees Celsius using liquid nitrogen). Gene banks are specifically designed to conserve the genetic diversity of endangered species.

5. **Defining Herbarium**: A herbarium is a collection of preserved plant specimens used for documenting plant diversity and providing reference for identification. It does not store genetic material but rather dried plant samples.

6. **Conclusion**: Since the question specifically asks about the storage of plant genes of endangered species, the correct answer is **Gene Bank**. Gene banks are specifically designed to preserve the genetic material of endangered species, making them the appropriate choice.

**Final Answer**: Plant genes of endangered species are stored in **Gene Banks**.
