During the autumn season, when the leaves fall, how do the plants and trees survive and where do they store the starch?

In the autumn season, perennial plants drop their leaves in a controlled manner to reduce injuries to the plant and conserve energy. The woody part of the trees or plants survives the cold.

Thus, the above-ground part of herbaceous plants (leaves, stalks) die, but underground parts (roots, bulbs) remain alive.

The plant undergoes dormancy for the long winter months. These plants live upon the stored food into their roots and sometimes stems.
