BIOL 2030 Study Guide - Final Guide: Plasmodium Vivax, African Trypanosomiasis, Contractile Vacuole
Document Summary
Rhizopodans: locomotion by lobopodian, filopodia and cytoplasmic flow. Long flagellum acts as a sensory organelle for exploring the surroundings. Plasmodium causes malaria; plasmodium vivax is the causative agent of malaria and accounts for 80% of the total numbers of infections worldwide. Rbc"s and form a ring cell stage (called a trophozoite makes a vacuolar stage and sends nucleus to one side) Trichocysts: small bodies in the ectoplasm that expel a long thread-like structure when simulated used in defense. Water enters via the incurrent pores on the sponge wall; then passes through the incurrent canals into the radial canal; the radial canal are line with choanocytes; radial canals lead to spongocoel and exit through osculum. Choanocytes: generate feeding current, as well as phagocytize food particles. Pinacocytes: secrete a substance that allows the sponge to firmly attach to its substrate. Two main types of polyps: gastrozooids (feeding polyp) and gonozooids (for asexual reproduction)
