Question

What is common to the techniques (i) in vitro fertilisation, (ii) Cryopreservation and (iii) tissue culture ?

• A. All are in situ conservation methods
• B. All are ex situ conservation methods
• C. All require ultra modern equipment and large space
• D. All are methods of conservation of extinct organisms

Answer 1

Answer: (B)

All are ex situ conservation methods

Answer 2

Conservation of biodiversity can be broadly classified into two types : In situ (on-site) and ex situ (off site). In situ is the preferred method to maintain species of wild animals in their natural habitats. This approach helps in conservation of total ecosystem. Ex situ approaches include conservation of those organisms, whose species may become extinct or decline heavily in number (due to a variety of reasons) in their natural habitat. This includes seed banks, cryopreservation, tissue culture, in vitro fertilisation, etc.
