the cell structure is arranged in what?
hyphae
what are protists?

what is symbiosis?
the interaction between two species
what is bacteria?
a prokaryote with no nucleus, cytoplasm, cell wall/ membrane, or ribosomes
what is a virus?
a tiny nonliving particle that invades and then multiplies inside a living cell
what is the definition of fruiting bodies?
where spores are produced
what are protozoans?

what is mutalism?
when both partners benefit from living together
what are flagella?
long whip-like structures for movement
what is a host?

what are surface proteins?
they are like keys for viruses to get in

what is algae

what is binary fission?
when one cell divides into two new cells
what are parasites?
organisms that live on or in a host
what are decomposers?
they are able to break down chemicals/substances.
what is a contractile vacuole?
a structure that collects the extra water and then expels it from the cell
tiny cells that are able to grow into a new organism
two cells. one transfers genetic material to the other then binary fission happens
what is bacteriophage?
a virus that infects bacteria
what is the definition of lichen?
the autotrophic bacteria that band together to create a mutalistic relationship
what is cilia?
hairlike projections from the cell that moves with a wavelike motion

food and right temperature
what are endospores?
small round cells inside bacteria
a substance introduced into the body to stimulate the production of chemicals that destroy specific diseases causing viruses and organisms
