Desiccation and mechanical damage

Vedclass · Answer

(A) When the temperature drops below freezing,the water inside the plant cells freezes. This leads to the formation of ice crystals,which cause mechanical damage to the cell walls and membranes. Furthermore,the freezing of water outside the cells creates a water potential gradient that draws water out of the cells,leading to severe desiccation (dehydration) of the plant tissues. Both these factors combined result in the death of the plant.
