organisms that typically reproduce by asexual budding or fission and whose nutritional mode is absorption or photosynthesis or chemosynthesis

(microbiology) single-celled or noncellular spherical or spiral or rod-shaped organisms lacking chlorophyll that reproduce by fission; important as pathogens and for biochemical properties; taxonomy is difficult; often considered to be plants

one-celled monerans having simple cells with rigid walls and (in motile types) flagella

a lash-like appendage used for locomotion (e.g., in sperm cells and some bacteria and protozoa)

aerobic rod-shaped spore-producing bacterium; often occurring in chainlike formations; found primarily in soil

any spherical or nearly spherical bacteria

a bacterial cell intermediate in morphology between a coccus and a bacillus; a very short bacillus

any flagellated aerobic bacteria having a spirally twisted rodlike form

spindle-shaped bacterial cell especially one swollen at the center by an endospore

one-celled monerans having simple cells with rigid walls and (in motile types) flagella

a lash-like appendage used for locomotion (e.g., in sperm cells and some bacteria and protozoa)
