Cryopreservation of gametes of threatened species in viable and fertile condition can be referred to as
in situ conservation by sacred groves
in situ cryo-conservation of biodiversity
in situ conservation of biodiversity
advanced ex situ conservation of biodiversity.
advanced ex situ conservation of biodiversity.
Solution
Cryopreservation is an advanced method of ex situ conservation. It involves preservation at -196 o C in liquid nitrogen. It can maintain tissue culture, embryos, animal cells/tissues, spermatozoa indefinitely. The cryopreserved material is revived through special technique, when required. dry weight of tobacco, with biosynthesis taking place in the roots and accumulation occurring in the leaves. Strychnine is an alkaloid plant toxin extracted chiefly from Nux vomica', formerly used as a stimulant. These are not metabolic disorder products but are metabolic wastes.
