NEET BIOLOGY

Detailed explanation-1: -Cells of cold tolerant plants survive the winter by entering a deep state of dormancy, known as endo-dormancy.

Detailed explanation-2: -A plant adaptation that helps it survive freezing temperatures and lack of liquid water is DORMANCY.

Detailed explanation-3: -Dormancy is defined as the temporary inability of a viable seed to germinate under favorable environmental conditions (Simpson, 1990). Dormancy helps the seed to survive adverse environmental conditions and at the same time helps in seed dispersal (Snape et al., 2001).

Detailed explanation-4: -At a temperature just above freezing, it is like the plant puts on a coat. The plant flips on a special protein called CBF, which acts like a master switch to turn on many other proteins, ultimately making the plant freezing-tolerant.
