The branches that arise from the stem which is very close to the surface of the ground break off from the parent plant and develop new plants. These branches are classified as follows: Runners - For example, strawberry, grass, etc. Suckers - For example, mint, Chrysanthemum ..

The male reproductive system comprises of a pair of testes that are present in a thin-walled sac called the scrotum . The scrotum is contained within the abdominal cavity in the embryonic stage. Shortly before birth, they come down and remain outside throughout life. This is because t..
