how do they reproduce?
It reproduces through binary fission, a form of asexual reproduction.

what bacterial parts are vital to a bacterium Prokaryotic microorganisms what do you mean by bacteria? They are a type of biological cell. describe their intracellular structures? It is surrounded by a cell membrane which encloses the contents of the cell and acts as a barrier to hold nutrients, proteins and other essential components of the cytoplasm. and extracellular? Around the outside of the cell membrane is the cell wall. Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by peptides containing D-amino acids. what are their origins? The ancestors of modern bacteria were unicellular microorganisms that were the first forms of life to appear on Earth, about 4 billion years ago. how about their metabolism? It exhibit an extremely wide variety of metabolic types which is classified into nutritional groups on the basis of three major criteria.

Bacteria [SEP] Growth and reproduction
Unlike in multicellular organisms, increases in cell size (cell growth) and reproduction by cell division are tightly linked in unicellular organisms. Bacteria grow to a fixed size and then reproduce through binary fission, a form of asexual reproduction. Under optimal conditions, bacteria can grow and divide extremely rapidly, and bacterial populations can double as quickly as every 9.8 minutes. In cell division, two identical clone daughter cells are produced. Some bacteria, while still reproducing asexually, form more complex reproductive structures that help disperse the newly formed daughter cells. Examples include fruiting body formation by "Myxobacteria" and aerial hyphae formation by "Streptomyces", or budding.
