Antibiotics - Substances that can kill bacteria. Bacteria - Prokaryotic organisms that have a single, circular chromosome and a cell wall. Binary fission - A method of asexual reproduction in which the bacterial cell divides in two. Capsule - A mucus-like layer that surrounds some bacteria. Cell membrane - A structure that controls entry and exit of substances to and from the cell. Cell wall - A structure made of cellulose that maintains the shape of a bacterial cell. Colony - A group of microorganisms of the same type. Cytoplasm - The fluid inside a cell. Decomposer - An organism that breaks down dead material. Eukaryote - A type of cell that has a proper nucleus. Extracellular digestion - Bacteria use this type of digestion. Activity Flagellum - A whip-like structure that allows a bacterial cell to move. Incubating - When microorganisms are put in conditions to encourage growth. Inoculating - When bacteria are put onto an agar plate or broth for culturing. Microorganisms - Organisms that are usually only visible through a microscope. Multicellular - A type of organism that consists of more than one cell. Parasite - A harmful organism that lives in or on another organism. Prokaryote - A type of cell that doesn’t have a proper nucleus, e.g. bacteria. Unicellular - A type of organism that consists of only one cell.
