sporozoite - daughter cell resulting from sporogony trophozoite - active, feeding stage of a protozoan, in contrast to a cyst schizogony - form of asexual reproduction in which multiple mitoses occur, followed by simultaneous cytokinesis, resulting in many daughter cells at once merozoite - daughter cell resulting from schizogony gametogony - process by which gametes are produced in protozoa; occurs when merozoites entering red blood cells transform into gametocytes

Complements circulate freely in blood plasma. True or False? - True Name the three ways complements can be activated by - Classical pathway, alternative pathway, and lectin pathway. The lectin pathway occurs spontaneously. True or False? - False; it has to do with the cell wall polysaccharides of bacteria and fungi The classical pathway refers to the antigen-antibody complex. True or False? - True. Opsonization - makes pathogen "tasty" for phagocytic cells like macrophages and neutroph...
