binomial nomenclature
two-word naming convention for each type of organism, which includes genus and species name
chromosome
structure that contains DNA, the genetic material passed from one generation to the next
cilium (plural, cilia)
small, hairlike projection from cells; can be used for motility or sensing the environment

bacterium with a round or spherical shape
endoplasmic reticulum (ER)
network of membranes that helps process molecules in a cell and transports cell materials
endospore
a toughened, condensed form of cell that can withstand harsh environmental conditions
flagellum (plural, flagella)
thread-like tail that allows some cells to move
glycocalyx
extracellular layer of polysaccharides and glycoprotein that coats the cell membrane
