In the liquid nitrogen, Pollen grains stored for some years having the temperature of -196oC.

 

This method of saving is called Cryopreservation.

 

The low temperature allows storing for a longer period by reducing the growth rate of cells.

 

The Cryoprotective agents delay the aging of the plants and protect the plants from the damages due to cold.

Pollen grains can be stored for several years in liquid nitrogen having a temperature of -196 degree Celsius.

Explanation:  

  • The pollen grains are a part of the male reproductive system of a plant. They are the haploid male gametes that fuse with the female gametes to give rise to a zygote after fertilisation.  
  • Under unfavourable conditions, these pollen grains are stored in order to fertilize them at other favourable conditions at times of need.
