Question

some plants in temperate regions shed their leaves before winter give reasons​

Answer 1

Answer:

During winter, there is not enough light or water for photosynthesis. The trees live off the food they had stored during the summer. They thus begin to shut down their food-making factories. ... This means that the cells cannot survive winter where temperatures fall below freezing.

Answer 2

Answer:

The shedding of leaves occurs at two different periods. The deciduous trees, i.e., the trees that grow in areas where snowfall bound winters occur, these trees shed their leaves in winter to survive the harsh weather. ... The trees beginthe shedding by cutting down the production of a plant growth hormone called Auxin.
