Plants and animals that are rooted to the ground aren't able to get up and find a partner to mate with, so being able to reproduce on their own is a great option! Natural propagation involves the growth of new plants from the specialized parts of a parent plant without the interference of the human. Species that reproduce sexually (and have separate sexes) must maintain two different types of individuals, males and females. In this type of reproduction, the genes of parents do not get diluted by those of other individuals.
