Definition: The production of new individuals have the same characteristics of the origin of a parent and without the formation of sexual cells.
Types:
First: Reproduction with bilateral fission:
- The cell is divided into two cells and occurs in single-cell organisms.
- such as bacteria (transverse), such as primates such as bramacium (transverse) and igloina (longitudinal).
Second: Reproduction with sprouts:
- The emergence of a bud (protrusion) on the side of the cellular wall grows gradually.
- occurs in some fungus (yeast) and some of the digestive (hydra).
Third: Reproduction by spawning:
- Cells called spores are formed within bogus portfolios (harsh environmental conditions).
- occurs in lichens, fungi and algae.
Explain the example of mushroom bread mold:
Spores are formed in portfolios and carry the caps on the pregnant, and when the spores mature, they press the bags and get out and then fall to the ground, and when the appropriate environmental conditions sprout form a new.
Fourth: Reproduction by renewal:
- The ability of the organism to compensate for missing parts.
- Occurs in the thorns of the skin and sponges.
Fifth: Fertilization:
- the ability of some animals to produce non-fertilized eggs with the ability to grow to form a new individual without fertilization.
- occurs in crustaceans and some worms and insects.
Sixth: Vegetative reproduction:
It does not require the presence of seeds.
