Types of Microbes Protozoa (pl.) / protozoan (s.) unicellular eukaryote classified based on type of locomotion: o sarcodines (sarco=flesh) move by pseudopodia (false feet), extensions of cytoplasm and cell membrane o mastigophorans (mastigo=flagella) flagellated, long whip-like extension of cell membrane o ciliophorans – move by cilia, short hair-like extensions of cell membrane o apicomplexans – no movement by pseudopodia, cilia, or flagella variety of shapes free-living or parasitic reproduction sexual or asexual Algae (pl.) /alga (s.) - mainly unicellular eukaryotes, few multicellular forms - photosynthetic - wide variety of shapes - reproduction sexual and asexual - cell walls composed of cellulose Viruses (pl.) / virus (s.)

Unformatted text preview: acellular (not quite a true cell) very small, only seen with electron microscope consists of a core made of only one type of nucleic acid (DNA or RNA) core surrounded by a protein coat sometimes the coat is encased by an additional layer, lipid membrane called envelope can only reproduce in a host cell using the host’s cellular machinery meaning they are parasitic and cannot survive without a host on the border between living and nonliving Multicellular animal parasites not microbe called the helminthes (helmin = worm) divided into two groups: o flatworms – dorsoventrally flattened, nonsegmented o roundworms – cylindrical in shape, nonsegmented are microscopic during some life stages...
