Question

One morning as Paheli 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

The small plants which were not there in the garden a week ago may have grown due to random seed dispersal by agents of pollination like wind, birds, water, animals. These seeds on germination in a suitable environment must have germinated into fresh new plants.
