Cell Theory – all living things are
made up of one or more cells.
Prokaryote – any single cellular
organism that does not have a nucleus.
Eukaryote - any multi cellular
organism whose cells contain a nucleus
and other organelles.
Unicellular - a single-celled organism,
is an organism that consists of only one
cell.
Multicellular – an organism that has
many cells.
Organism - an individual animal,
plant, or single-celled life form.
Cell - the basic structural unit for all
organisms.

Response – a reaction of an
organism or any of its parts, to a
specific stimulus.
Impulse - a signal transmitted along a
nerve fiber.
Stimulus - a thing or event that
evokes a specific functional reaction in
an organ or tissue.
