Microbe Vocbaulary
Amoeba: an animal-like protist
Bacteria: unicellular organisms that lack membrane-bound
structures; a common term used to describe prokaryotes.
Capsid: the protein shell that surrounds a virus.
Capsule: a surface layer on some bacteria that helps them
stick to each other and surfaces.
Cilia: a short hair-like appendage used by microorganisms
for motion.
Euglena: unicellular protist that lives in freshwater
characterized by a reddish eyespot and a single flagellum
Eukaryote: either unicellular or multi-cellular organism that
contains membrane-bound organelles and genetic material
within a nucleus.
Eyespot: an organelle of the protist euglena that is sensitive
to light.
Flagellum: a whip-like structure on unicellular organisms
that aids with movement.
Microbe: any organism or near life form that cannot be
seen with the naked eye.
Paramecium: a protist.
Parasite: an organism that derives nourishment or habitat
from the tissues or fluids of another organism. A eukaryotic
pathogen can be unicellular or multi-cellular.
Prokaryote: a unicellular organism that lacks a true nucleus
and membrane-bound organelle.
Protist: generally, a single-celled organism with a nucleus
and organelles, including amoebas, euglenas, paramecia
and volvox.
Pseudopod: an extension of the cytoplasm used for
movement in some organisms. A means of locomotion for
an amoeba; literally, “false foot.”
Virus: a particle consisting of DNA encased in a protein
coat that must inject its DNA into a living cell in order to
reproduce. A microbe that consists of nucleic acid enclosed
within a protein shell that requires a living cell in order to
reproduce. Scientists consider the virus to be not alive.
