Question

how plants maintain their temperature in cold days?​

Answer 1

Plant cells survive sub-freezing temperatures by adjusting their solutes, proteins, and membrane lipids in order to withstand desiccation and to avoid ice crystal formation.

Hope this helps :)

Answer 2

Answer:

By using water, sugar and enzymes.

Explanation:

The water inside a cell expands as it freezes, becoming ice. This may result in cell death by rupturing the cell membrane. When it becomes chilly, plants respond by turning on metabolic processes that shield their cells from the cold and freezing temperatures. A defence tactic is to store sugar, which lowers the temperature at which ice forms and has a similar impact as applying salt to roadways. Another is to make proteins that keep membranes stable so they can withstand rupturing.
