What happens when plant tissues are frozen?

Answer 1

Usually, cellular damage and dessication.
Ice crystals forming are like tiny spears which pierce through cell membranes and cause extensive damage. At the same time, the freezing water causes osmotic imbalance, pulling water out of the cells and shriveling them.
Some plant tissues combat freezing by creating various organic forms of antifreeze in their cells.
Did you know even some amphibians do this? Wood frogs, for example.

Answer 2

this will break the tissues with the expanding of the ice ,but cells will stay intact and can be cloned
a lot depends on the plant there are millions of different plants all different in vibre,and cell structure
some smaller organisms can be frozen and will spring to life again when thawed
and many bulbs will survive frost,as seeds do

Answer 3

Water contained therein freezes, and the ice crystals formed are larger in volume than the water. This can damage or kill the tissues.

Answer 4

they are slowed down
