Question

Which of the following is ex situ conservation?

• A. Cryopreservation of gametes
• B. Breeding of animals in Zoological Parks
• C. Seed storage
• D. All of the above

Answer 1

The correct option is D All of the above

Ex situ conservation is an approach wherein threatened animals and plants are taken out from their natural habitat and placed in special settings where they can be protected and given special care. An example of ex situ conservation is the captive breeding of animals in Zoological Parks. However, in recent years, ex situ conservation has taken on a new agenda that goes beyond just ensuring physical protection and comfort of endangered species. Today, zoologists obtain gametes of threatened species and preserve them in viable and fertile conditions for long periods using cryopreservation techniques. Egg cells can also be fertilised in vitro. Seed storage thus, helps in ex situ conservation of plants.
