Asexual reproduction is widespread in nature, because this is the simplest and fastest way of reproduction. Asexual reproduction is carried out in several ways. For example, remember the reproduction of amoeba or other single-celled organisms, which reproduce by division. In this way, these living things give individuals the same as themselves.
Other living things, e.g. mushrooms, mosses, ferns multiply by spores. Spores are very small bodies that are carried by the wind, like dust, and then fall to the ground to give rise to other living things.
Another way of non-sexual reproduction is with bulbs (figure below).
So, in the body of the hydra, a bule appears, which is a multicellular mass, capable of living independently. The most widespread way of asexual reproduction is the vegetative one. Vegetative reproduction is particularly widespread in plants.
Remember the vegetative pruning, for example, of potatoes with tubers, onions, tulips, etc., with onions (bulbs), etc.
From the study of all ways of non-sexual reproduction, we can draw these conclusions:
1. During asexual reproduction, only one parent is needed.
2. It is a way of reproduction that requires a little time.
3. The individuals who are born are the same between themselves and the parent.
