Document Summary
Not present in eukaryotes that have cell walls: functions. Strengthens cell surfaces: cell wall, general. Located in fungi, algae, and a few protozoa. Functions in strength and maintaining the cell shape: structure. Contains cellulose, pectin, chitin, mannans, and minerals. Which structural components are present and concentrations of them depend on the organism: cell membrane, structure. Sterols (i. e. cholesterol) strengthen the membrane but maintain fluidity. Internal membrane bound structures: flagella and cilia, structure. Microtubules in a 9+2 arrangement run the length. Basal body (kinetosome) has a 9+0 arrangement. *9+2 is 9 pairs of microtubules surrounding a pair in the middle* *9+0 is 9 trios of microtubules with nothing at their center: movement. No runs and tumbles: differences, flagella. Located on the poles of the cells. *located on protozoa and animal cells, not on prokaryotes: nucleus, structure, surface, nuclear envelope. Outer membrane is continuous with the endoplasmic reticulum: nuclear pores.
