One of the most important functions of botanical gardens is that

  1. they provide a beautiful area for recreation
  2. one can observe tropical plants there
  3. they allow ex situ conservation of germplasm
  4. they provide the natural habitat for wild life.

Answer

(3) they allow ex situ conservation of germplasm

Solution

As per NCERT, in ex situ conservation threatened plants and animals are taken out of their natural habitat and protected in special settings; zoological parks, botanical gardens and wildlife safari parks serve this purpose.

⇒ Botanical gardens keep living collections of plants (germplasm) away from their natural habitat.

∴ Their most important function is ex situ conservation of germplasm. Recreation and viewing tropical plants are minor uses, and natural habitats are provided by in situ areas (national parks, sanctuaries), not gardens.

Answer: (3)
