This process generally occurs when environmental conditions are most favourable. That is, when there is enough food, water, and a favourable temperature. Binary fission is a type of asexual reproduction to produce young ones. Leishmania has a whip like structure at one end of the cell, hence binary fission occurs in a definite orientation in relation to this structure. In the stage of binary fission, the cell divides and forms 2 daughter cells. In amoeba, splitting of the cell into two during cell divison can take place in any plane. These include paramoecium, bacterium, and finally amoeba. In this paragraph we will be focusing on amoeba’s cell division which is also its method of reproduction. In binary fission the amoeba consists of one parent which forms the 2 daughter cells. First, the amoeba cell undergoes nuclear division and replicates into two nuclei. The two nuclei divide and move to opposite directions in the parent cell. The cell then produces protiens and nutrients in preperation for binary fission. Most single celled organisms use the method of binary fission for cell division and reproduction. Although they are fairly large cells, most amoebas are too small to see with the naked eye however, some species grow to grape size.Without a contractile vacuole, the amoeba would explode in a freshwater environment. Organelles called contractile vacuoles constantly fill with excess water, and pump it out of the cell. Amoebae that live in freshwater ponds must deal with water constantly rushing into the cell.Basically tiny predators, they feed mainly on other microorganisms. Amoebae ingest food through phagocytosis (the process whereby a cell engulfs a piece of food and ingests it).Most amoebae live in pond water, moist soil or the ocean some species are parasitic, living inside the body of another organism.Amoebae move when cytoplasm flows out into a long extension of the cell this crawling, flowing motion is called psuedopodia.Amoebae have organelles (including one or more nuclei) and a contractile vacuole. They have no definite shape and consist of flowing cytoplasm encased in a very flexible cell membrane. However, they can also exchange genetic material by joining to exchange DNA in a process called conjugation.Amoebae are single-celled, crawling organisms often found in ponds. Protozoans can produce haploid gametes that fuse through syngamy. Protozoans may also reproduce sexually, which increases genetic diversity and can lead to complex life cycles. The products of schizogony are called merozoites and they are stored in structures known as schizonts. In schizogony, the nucleus of a cell divides multiple times before the cell divides into many smaller cells. In protozoans, asexual reproduction occurs by binary fission, budding, or schizogony. Some protozoans reproduce asexually and others reproduce sexually still others are capable of both sexual and asexual reproduction. Amoeba is a unicellular organism, and just like bacteria, it reproduces through binary fission. Protozoans have a variety of reproductive mechanisms.
In this method, two similar individuals are produced from a single parent cell. After replicating its genetic material through mitotic division, the cell divides into two equal-sized daughter cells.
