Answer:
=> Binary Fision in Bacteria and Amoeba :- Amoeba is a unicellular organism, and just like bacteria, it reproduces through binary fission. After replicating its genetic material through mitotic division, the cell divides into two equal-sized daughter cells. In this method, two similar individuals are produced from a single parent cell
Binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
=> Multiple fission :- The nucleus of the parent cell divides several times by amitosis, producing several nuclei. The cytoplasm then separates, creating multiple daughter cells. Some parasitic, single-celled organisms undergo a multiple fission-like process to produce numerous daughter cells from a single parent cell.
=> Fragmentation and Budding :- Fragmentation occurs when a parent organism breaks into fragments, or pieces, and each fragment develops into a new organism. Budding occurs when a parent cell forms a bubble-like bud.
=> Parthenogenesis :- Parthenogenesis is a form of reproduction in which an egg can develop into an embryo without being fertilized by a sperm. Parthenogenesis is derived from the Greek words for “virgin birth,” and several insect species including aphids, bees, and ants are known to reproduce by parthenogenesis.
=> Spore formation in Bacteria :- Spores, also referred to as endospores, are the dormant form of vegetative bacteria and are highly resistant to physical and chemical influences. Disinfection measures for inactivating spores require a special spectrum of activity that covers both the bacterium's vegetative form and spores.
