A type of reproduction in organisms that does not involve the union of male
and female reproductive cells. Asexual reproduction occurs in several forms:
- fission –
the simple division of a single individual, as in bacteria or protozoa;
- budding – growing
out and eventual splitting off of a new individual, as in Hydra;
- spore formation –
as in fungi;
- vegetative reproduction – in which a plant
sends out runners that take root to forms new plants, as in strawberries,
or new plants grow from organs such as bulbs.
Vegetative reproduction may occur naturally (again, strawberries are a good example) or artificially, as in a house plant cutting yielding a new plant.
