cryopreservation is a technique in which plants explants are preserved at -1960 C.

use cryopreservation technique..
You take a small suspension of bacteria from a liquid culture, add it to a buffer (we use a glucose solution) and place it in a -50 -- -90 Celsius nitrogen freezer. Easy.
Simple plants are called plants. Simple plants are called plants.
Seed plants are actually flowering plants. Since the plants reproduce the flowers bloom from the plants. The seeds are carried to different places by the wind. Other plants such as the fern are called seedless plants because ferns do not reproduce by seeds they reproduce by spores.Added:Excepting gymnosperms, which are seed plants that do not flower.
Angiosperms are flowering plants
Vitrification is the preferred method for the cryopreservation of gametes. It involves freezing them quickly so that ice crystals do not form.

cryopreservation means storing of cells tissues etc at vry low temoeratures like 77k or-196centigrade using liqvid nitrogen

Freezing and thawing can destroy the cells, and this is not a processed used to preserve them. They can be preserved by cryopreservation by lowering the temperature to -196F.
Umbilical stem cells, the kind most easily obtained, are stored at cord blookd banks by cryopreservation (freezing to -196c). The lasting time of cryopreservation is theoretically infinite, although it is difficult to prove. After processing, PBSC are cryopreserved for later infusion. They are frozen using a special controled slow methode. They can last 10 years.

Cryopreservation works by slowing down the metabolism of cells until they can no longer function. This is done by lowering the temperature until all water in the cells freeze or is removed by osmosis.
