Test 3 Material

MOSTLY single celled eukaryotic. Known first eukarytoic cell. Over 200,000 species.

binary fission-asexual conjugation-sexual

divides into two cells. cloning

swapping micronuclei. causes genetic variation

water molds and slime molds like fungi, has fruiting bodies and absorbs nutrients from surrounding environment

slime mold moves around as single cells and begins to move together to form a large mass, swaps DNA fruiting bodies that has spores inside

In potatoes, in Ireland in 1845 fungal-like infection, wiped out crops. millions starved and many emigrated to US

phytoplankton, dinoflagellates, diatoms, algae, kelp, and seaweed

plant-like protista in ocean. with bacteria produce over 70 percent of oxygen on earth

Plant-like protista Red tide, giving of large amounts of toxins killed off manatees

Plant-like protista silica casing/glass casing significant to marine food webs lots of oxygen

plant-like protista example of multicellularity no variety in tissues, all one tissue. NOT plants

Animal-like protista highly mobile and heterotrophic move by various structures=cilia, flagellum,pseudopod

Camper’s curse, animal like protista infects GI tract, gives person diarrhea and abdominal cramping.

Plasmodium, animal like protista mosquito are carriers, affects liver

Trypanosoma, animal like protista vector is tste fly, gets into spinal fluid, lymph, and blood. host falls asleep then may die has undulating flagellum

multicellular protozoan, has daughter colonies present and rounded

single celled, flagellum highly mobile and has chloroplasts and photoreceptors plant like/animal like

tube-like, covered in cilia, spirals around endocytosis= food vacuoles contractile vacuole=holds water

long stalk with cilia on top one cell attaches on one side and other side does endocytosis

cup on spring filter feeds

Cytoplasmic streaming, uses proteins to push cytoplasm in one direction and makes pseudopods move forward Can also use as food vacuole, digests with enzymes

grows on rye, can make people hallucinate. During Salem Witch Trials many affected, blamed on witchcraft. Fungi

eukaryotic multicellular, except yeast not plants, no photosynthesis 100,000 species decomposers reproduce with spores
