Document Summary
Pseudopod: movement of amoeboid, move and feed by pseudopods, phagocytosis, malaria in feeding stage is amoeboid. Flagella: one or multiple, flagellum whip like in protozoan, low energy organisms usually. Cilia: fast, maneuverable, short coordinated, take more energy, extra energy=extra food capturing, can make currents to bring food towards you, not common. Alternation of generations: haploid gametophyte, haploid gametes, gametes fuse, diploid sporophyte, releases haploid spores, spores become gametophyte, allows for cross fertilization and self-fertilization. Haploid gametophyte (n) (mitosis) gametes (n) (mitosis) zygote (2n) sporophyte (2n) (can be single or multicellular) (meiosis) spores (n) (mitosis) . Spore phase is a dispersal phase, find new hosts and new areas to live. Sexual reproduction-diversity, asexual-rapid growth, and dispersal-much less control of dispersal, so key. Dinoflagellate: encased in cellulose (weird because that"s pla(cid:374)t (cid:373)ate(cid:396)ial, 2 flagellum, one on side, one wraps around center free living, parasitic, helpful found in red tides-dino create toxin that can paralyze respiratory.
