protist:
a one or many celled organism living in wet or moist environments
algae:
plantlike protists
flagellum:
long, thin whiplike structure used for movement
protozoans:
one celled, animal like protists
cilia:
short threadlike structures that extend from the cell membrane
pseudopods:
temporary extensions of the cytoplasm; means ‘false foot’
hyphae:
the body of a fungus and a root network
saprophytes:
organisms that obtain food from dead organisms
spore:
waterproof reproductive cell that can grow into a new organism
basidium:
spores produced in a club-like structure
