Question

In situ germplasm conservation is done by
A. Biosphere reserve
B. Germplasm banks
C. Pollen banks
D. Botanical gardens

Answer 1

Hint: In situ conservation means the conservation of different kinds of plant and animal species in their natural habitat.

Complete Answer:
1. Biosphere reserves – Biosphere reserves are the areas that are used to conserve biodiversity. These areas contain many national parks and wildlife sanctuaries. These areas help in the conservation of various types of plants, animals and microorganisms in their natural habitat.

2. Germplasm banks – Germplasm bank is the collection of live plant matter in the form of seeds and spores. It comes under ex-situ conservation which means the conservation of species outside their natural habitat.

3. Pollen banks – Pollen banks are used to store pollens for a very long period of time in viable conditions at very low temperature using liquid nitrogen. It also comes under ex situ conservation.

4. Botanical gardens – Botanical garden is a garden which is dedicated to the collection, cultivation, preservation and display of a wide range of plant species. Here each plant species is labeled with its botanical name. These gardens are man made so this also comes under the category of ex situ conservation.

In situ germplasm conservation: In situ germplasm conservation means the preservation of live plant matter in the form of seeds and spores in their natural habitat.

So, the option A is the correct answer for this question.

Note: As we know that due to some human activities many species of plants are extinct and some are endangered. So in order to protect the extinction of species, conservation is must and should be required.
