Modern ex situ conservation includes which of the following?

(a) Cryopreservation techniques 

(b) In vitro fertilisation

(c) Tissue culture methods 

Ex situ conservation is a method of removing threatened animals and plants from their native environment, and placing them in a particular area where they can be protected and cared for. Ex situ conservation has progressed in recent years beyond the confinement of threatened species. Threatened species' gametes can now be frozen in a viable and fertile state for long periods using cryopreservation techniques. Eggs can be fertilised in vitro, and plants can be grown utilizing tissue culture procedures. Seeds of various genetic strains of commercially important plants can be stored in seed banks for long periods of time as well.
