Bacteria reproduce by a process known as binary fission, while eukaryote such as animal cells, reproduce by mitosis. In binary fission one bacterium slowly separates into two bacteria which then also divide and the life cycle continues as this process repeats over and over.
Sexual reproduction is a biological process that creates a new organism by combining the genetic material of two organisms in a process that starts with meiosis, a specialized type of cell division. Each of two parent organisms contributes half of the offspring's genetic makeup by creating haploid gametes.
