Vedclass · Answer

(A) Plants are killed in winter by frost primarily due to desiccation and mechanical damage to the tissues. When temperatures drop below freezing,ice crystals form within the intercellular spaces of the plant tissues. This process causes the withdrawal of water from the cells (desiccation) and the physical rupture of cell membranes and walls due to the expansion of ice,leading to tissue death.
