उत्तर
(i) It is an example of ex-situ conservation (off-site conservation). In this approach, threatened plants and animals are taken out of their natural habitat and placed in to suitable settings and given special care.
(ii) Cryopreservation and tissue culture are two ways that help in ex-situ conservation.
In cryopreservation, gametes of threatened species are preserved in viable and fertile conditions at sub-zero temperatures, which help in preserving these cells for longer periods.
In tissue culture, plants are propagated from a small mass of tissue, called callus.
