Document Summary
Usually intracellular in host: invade individual cells. Pushes inside the host creates a vacuole inside the host cell made up of cell membrane. Often have complex life cycles: usually sexual, often with two hosts. Cell organization: features that give away evolution, no flagella glides, have alveoli. Micropore hole in alveolus involved in acquiring nutrients: secretory vesicles at anterior end apical complex. Evolved for host cell invasion: apicoplast compartment surrounded by 4 membranes. Plastid descendent of photosynthetic apparatus of algae. Is no longer photosynthetic essential for other biosynthetic functions. Life cycle: haploid dominant life cycle (diatoms have diploid dominant, may involved multiple hosts, three main cell types. Gametes: sporozoite production includes a meiotic step, reproduction by multiple fission o, in mosquito. Sporozoites (n) are injected into the human by mosquito sporozoites invade the liver and make mesoziotes (n) through asexual reproduction mesozoites (n) invade the red blood cells: mesozoites can enter a quiet form (non-reproducing) gametocytes.
