Answer
Ex-situ conservation (Off-site conservation):
This approach involves placing threatened animals and plants in special care units for their protection.
India has 35 botanical gardens and 275 zoological parks where animals which have become extinct in wild are maintained.
By using cryopreservation (preservation at -196°C) technique, sperms, eggs, animal cells, tissues and embryos can be stored for long period in genes banks, seed banks, etc.
Plants are propagated in vitro using tissue culture methods (micropropagation).
It is the desirable approach when urgent measures to save extinction are required.
