Document Summary

Protists: eukaryotic origins, eukaryotic cells differ from prokaryotes due to their presence of a cytoskeleton and compartmentalisation, evolution of nucleus and endoplasmic reticulum, nucleus and endoplasmic reticulum, many modern prokaryotes have infoldings. Cysts: tissue cysts develop i(cid:374) host"s orga(cid:374)s i(cid:374) respo(cid:374)se to i(cid:373)(cid:373)u(cid:374)e syste(cid:373, oocyst dormant structure with resistant outer protein covering. Locomotion: flagella one or more, cilia shorter and more numerous than flagella, pseudopodia false feet. Nutrition: phototrophs autrotrophs through photosynthesis, heterotrophs phagotrophs (ingest particulate food matter) and osmotrophs (soluble food matter, mixotrophs both phototrophic and heterotrophic. Reproduction: asexual, mitosis equal sized daughter cells, multiple fission schizogony in apicomplexans, budding unequal sized daughter cells, sexual, meiosis, haploid daughter cells, fertilization, genetic recombination. Excavata: among earliest eukaryotes, basal unicellular flagellate organisms, many lack functional mitochondria, have a feeding groove on the side of the body, no ecm, one third have chloroplasta, reproduce asexually. Choanoflagellates: fungi, unicellular, common ancestor of sponge.
