Question

Define asexualreproduction. Describe two methad of asexual reproduction in animal for 8th class

Answer 1

Answer:

Explanation:

Definition:

Asexual reproduction is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes, and almost never changes the number of chromosomes.

Methods:

               1.Budding: Some cells split via budding resulting in a "mother" and "daughter" cell. The offspring organism is smaller than the parent. Budding is also known on a multi-cellular level; an animal example is the hydra, which reproduces by budding. The buds grow into fully matured individuals which eventually break away from the parent organism. Examples: Yeast, Hydra.

               2.Fission: An important form of fission is binary fission, where the parent organism is replaced by two daughter organisms, because it literally divides in two. Example: Amoeba, Bacteria
