Question

Suggest four advanced ex-situ methods to conserve threatened biodiversity?

Answer 1

Techniques for plants:-
1.Cryopreservation

2.Seed banking

3.Tissue culture (storage and propagation)

4.Field gene banking

5.Cultivation collections

6.Inter situ

Answer 2

Ex situ conservation is a off-site conservation in which biodiversity is protected out of its natural habitat.

Explanation:

Ex situ conservation is widely used to protect endangered or threatened bioderviersity. Advanced ex-situ methhods for biodiversity conservation are as following:

1. Methods for plant conservation:

• Cryopreservation : in this method the seeds, polle, tissue or embryos are stored in liquid nitrogen. it prevent deterioration over long time and a palnt specied can be conserved.
• Seed banking : In this method seeds are conserved and stored at a particular temperature and moisture. this method prevent desiccation and further protect endangered species.

    2. Methods for animal conservation:

• Gene Bank: In genebanks, sperms or eggs or embryos are stored which are provided all cryogenic facilities.
• Interspecific pregnancy: In this method embryo of endagered species is implanted into the uterus of related species.
