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

Options

A. a) All are in situ conservation methods.
B. b) All are ex situ conservation methods.
C. c) All require ultra modern equipment and large space.
D. d) All are methods of conservation of extinct organisms.

Answer

B

Explanation

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