Plants reproduce vegetatively, without needing seeds, using their vegetative organs such as leaves, roots and stems, and their cells (tissue culturing) in order to produce new plants very similar to the parent plant.

When spores find a suitable environment, they start growing to create a new organism. Each sporangium has a large number of spores that release after rupturing its wall.

This type of asexual reproduction is more common in some fungi such as bread mold, mushrooms and some algae, where they have special organs called sporangia (a singular sporangium).

For example, starfish arms can be regenerated and create a complete animal if they contain a part of the central disc of the animal. The living organism can reproduce one of its parts.

Regeneration is the ability of animals to compensate their missing parts.A bud grows gradually and remains connected to the parental cell until is fully grown then separates from it or remains to form a colony.One of them remains in the parental cell and the other immigrates to the bud. In yeast, the bud emerges as a lateral bulge in the cell, then the cell nucleus is divided (by mitosis) into two nucleoli.This occurs in unicellular living organisms (such as yeast fungus) and multi-cellular organisms (such as Hydra and Sponges).This type of division occurs in unicellular protozoans such as Amoeba, Paramecium and Euglena and also in simple algae and bacteria.The nucleus is divided by mitosis and then the cell which represents the body of the unicellular organism splits into two cells. This is a type of asexual reproduction that occurs in unicellular living organisms.The following are some types of asexual reproduction: Asexual reproduction includes mitosis and does not require special systems or structures in the living organisms.

Asexual reproduction usually occurs in unicellular living organisms, but it also occurs in some multicellular animals and plants where a living organism produces new individuals that have genetic traits identical to the parents.It occurs through two living organisms, one of them is a male and the other is a female. Sexual reproduction: this occurs in higher living organisms of plants and animal.It mostly occurs in single-celled living organisms such as budding in yeast and binary fission in Amoeba. Asexual reproduction: this occurs by only one living organism.Types of reproduction in living organisms: In this process, the genetic traits move from parents to offspring. Reproduction is a biological process where the living organism produces new individuals of the same kind and thus ensuring its continuity. Living organisms are characterized by their ability to reproduce.

Mitosis produces two identical daughter cells with the same number of chromosomes as the parent cell.
