Question

One morning as Leena strolled in her garden she noticed many small plants which were not there a week ago. She wondered where they had come from as nobody had planted them there. Explain the reason for the growth of these plants

Answer 1

This may have occurred due to seed dispersal. Sometimes seeds are transported away from the parent plant via wind, water, etc. On reaching to a certain place they give rise to a new plant at that place.
