The document discusses various modes of asexual reproduction including fission, mitotic cell division, budding, regeneration, vegetative reproduction, and cloning. Asexual reproduction involves a single parent producing offspring that are genetically identical through mechanisms such as cell division, budding off of new individuals, or regeneration of new individuals from fragments of the parent. Many different types of organisms, including fungi, bacteria, protists, plants and animals, are capable of asexual reproduction.
