2.2.1 - Asexual Reproduction

Asexual reproduction

A mode of reproduction in which a single parent reproduces without the fusion of egg and sperm.

Fission

The division of a parent cell into two or more cells, occurring in types such as binary and multiple fission.

Binary fission

A process where a parent cell replicates its genetic material and divides into two equal-sized, genetically identical daughter cells.

Multiple fission

A type of fission where a parent cell divides into many genetically identical daughter cells.

Budding

A form of asexual reproduction where small buds grow on the side of the parent cell and develop into identical daughter cells.

Fragmentation

A form of asexual reproduction in which the body of a multicellular organism divides into parts that develop into new individuals.

Vegetative reproduction

A form of asexual reproduction in plants where fragments develop into genetically identical plants.

Spore formation

A reproductive process that produces spores which can develop into new organisms without fusing with another reproductive cell.

Parthenogenesis

A form of asexual reproduction where embryos develop from unfertilized eggs, resulting in offspring that carry the mother's genetic material.

Advantages of asexual reproduction

Includes no need for a mate, quicker reproductive cycles, and rapid production of numerous offspring.

Disadvantages of asexual reproduction

Includes limited genetic diversity, vulnerability to environmental changes, and the potential for overpopulation.
