________ any eukaryote that is NOT a plant, animal, or fungus.
- Mostly single-celled and microscopic in size.
____ are single-celled protists that live mostly in fresh water and are named after the group's best-known representative, Euglena, a complex single cell that moves about by whippings it flagellum through water.
A member of a protist group that includes species with filamentous shapes that give them a superficially fungus-like appearance.
_______photosyntheic stramenopiles found in both fresh and salt water, produce protective shells of silica (glass).
A multicellular and photosynthetic protist.
______includes photosynthetic and non-photosynthetic organisms, organisms have a flagella and vary in the number of cells.
____ are single-celled organisms that have distinctive, small cavities beneath the surface of their cells.
_____a member of a protist group that includes photosyntheic forms in which two flagella project through armor-like plates; abundant in oceans; can reproduce rapidly, causing "red tides"
The explosive reproductive rate of certain dinoflagellates under the right enviromental conditions can produce concentrations so great that their microscopic bodies dye the seawater red or brown, as in this bay in Mexico.
A red tide
______are parasitic living inside the bodies and sometimes inside the individual cells of their hosts.
