Sessile or motile >10 microns Worms, snails, insects, mammals, birds Wet mount Staining YES NO YES NO True color and shape Organism alive Advantage (s) Easy to perform Difficult to locate and observe fine details Disadvantage (s) (organism moving, microbes are translucent) Organism more visible, visualization of differences between organisms Require more time, reagents, supplies, and skills Some useful word roots: cili- = hair (cilium: a short hair-like cellular appendage) eu- = true; karyo- = nucleus (eukaryotic cell: a cell that has a true nucleus) flagell- = whip (flagellum: a long whip-like cellular appendage) pro- = before (prokaryotic cell: a cell that has no nucleus) pseudo- = false; -pod = foot (pseudopodium: a cellular extension of amoeboid cells) MONERA PROTIST PLANTAE FUNGI ANIMALIA
