Asexual reproduction is reproduction without sex.
Types of asexual reproduction[change | change source]
Binary fission[change | change source]
Some organisms like bacteria reproduce using binary fission. They split in two, so one bacterium becomes two bacteria. This always leads to daughter cells, and the offspring will be identical to the parent.
Budding[change | change source]
Budding is similar to binary fission, but it is used by plants and some animals, which cannot simply split in half as bacteria can. It is when a small part of a plant or animal breaks off and then, while they are separated from their "mother", they start to grow until both the "parent" and the "offspring" are the same size and both are capable of budding again. This may happen many more times.
Spores[change | change source]
Fungi (for example, mushrooms) produce spores, which may be asexual or sexual. The asexual spores have the genetic material inside, which allows them to make a whole new organism identical to its parent. They are produced by mitosis. Different fungi make different kinds of asexual spores, conidia, oidia, and pycniospores. The shape and colour of the spores can be helpful to identify the species of fungus.
Sexual vs asexual reproduction[change | change source]
|Asexual reproduction||No mate needed. Many offspring produced quickly||No variation in the offspring.|
|Sexual reproduction||Genetic variation in the offspring.||Requires both sexes to participate.|
