9. Define Saprobe: A microbe that decomposes organic remains from dead organisms
10. Define Parasite An organism that lives in or within a host from which it obtains nutrients and
enjoys protection. Produces some degree of harm to host
11. Define Diffusion: movement from high to low
12. Define Osmosis: Diffusion of water through a selectively permeable membrane
13. hypotonic cell: cells that are less concentrated than their environment; water rushes in, may
burst cell
14. hypertonic cell: cells that are more concentrated than their environment; water rushes out of the
cell causing it to shrivel
15. isotonic cell: extracellular environment has the same concentration of solutes as the cell
cytoplasm
