Answer:
Most animals and plants come from two parents. Each new organism is unique, a mixture of both parents' characteristics. However, some organisms can reproduce from only one parent. These new organisms are identical to the parent. The process of reproducing from only one parent is called asexual reproduction.
Examples:
Organisms such as amoebas and bacteria reproduce through binary fission. An organism splits in half and becomes two separate organisms.
Organisms such as hydras, sponges, and some yeast reproduce through budding. A new individual develops on the parent organism and grows until it is able to survive on its own. At that point, it breaks off from the parent and lives on its own.
Planarians can reproduce by fragmentation. These small flatworms sometimes break into many tiny fragments. Each fragment can grow into a new planarian.
A few organisms can reproduce through regeneration. For example, if the arm of a sea star is broken off and it includes a piece of the center of the sea star, then that arm can grow to become a new sea star.
