Fragmentation

is a type of asexual reproduction wherein a single parent breaks into parts that give to a new individual.

Budding

involves the splitting of new individuals from an existing organism by forming small projections, called buds, from the parent’s body.

Binary Fission

happens to microsome, one cell organisms. It grows and splits

is a form of asexual reproduction in some animals that give to the growth and development of an embryo without fertilization.

Reproduction

is the process of generating new individuals of the same kind to ensure the continued existence of the species.
