multiple flagella, two seperate nuclei, a relatively simple cytoskeleton, no plastids, no mitochondria
lacks mitochondria, includes the protists called trichomonads. vagina disease.
anterior pocket, or chamber, from which one or two flagella emerge. Paramylon, a glucose polymer that functions as a storage molecule, is also characteristic.
Single large mitochondrion associated with a unique organelle, the kinetoplast, that houses extranuclear DNA. sleeping sickness.
Dinoflagellates, Apicomplexans, and Ciliates. Have small membrane- bounded cavities under their cell surfaces. this may help stabilize the cell surface and regulate the cell's water and ion content.
Make up a large proportion of the phytoplankton at the base of most marine and many freshwater food chains. Two flagella between internal cellulose plates. Responsible for harmful red tides.
tiny infectious cells that spread apicomplexans
Use cilia to move and feed. Have two nuclei.
Includes algae, all groups characterized by hairlike projections on the flagella.
Important decomposers in aquatic ystems
White rusts and downy mildews
Destructive parasites of land plants
Common unicellular marine and freshwater plankton with unique boxlike silica walls.
largest and most complex algae
no flagellas,absorb wavelengths of light that would otherwise go to deepest water
Plasmodial slime molds
Heterotrophic, engulfin food particles by phagocytosis
