Question

Cryopreservation is germplasm protection by

• A. Crossing with wild varieties
• B. Energy flow in different trophic leak
• C. Both A and B
• D. Low temperature

Answer 1

The correct option is D Low temperature

Cryopreservation is germplasm protection by low temperature. It is the process in which organelles, cells, tissues, organs are prevented from damage caused by unregulated chemical kinetics by preserving it at low temperatures. The temperature used is typically −80${}^0$C using solid carbon dioxide or −196${}^{)}$C using liquid nitrogen.

So, the correct answer is 'Low temperature'.
