Solution

It is a common observation that green grass plants spring up in dry fields after the rains.

This happens due to vegetative propagation as follows : The fields have dry stems of the old grass plants all over them.

These dry stems have buds which are in the inactive state.

By getting rainwater, the buds present on dry grass stems get activated and grow to produce new grass plants.

Thus, the green grass grows in the fields after rains from the dry, old stems of grass plants present in the fields, by the method of vegetative propagation.
