Document Summary
Basal body: an organelle that forms the base of a flagellum or cilium. Cell theory: states that cells are the basic structural and physiological units of all living organisms, and that all cells come from preexisting cells. Cell wall: a relatively rigid structure that encloses cells of plants, fungi, many protists, and most prokaryotes, and which gives these cells their shape and limits their expansion in hypotonic media. Chloroplasts: an organelle bounded by a double membrane containing the enzymes and pigments that perform photosynthesis. Cilia: hair-like organelle used for locomotion by many unicellular organisms and for moving water and mucus by many multicellular organisms. Collagen: a fibrous protein found extensively in bone and connective tissue. Cytoplasm: the contents of the cell, excluding the nucleus. Cytoskeleton: the network of microtubules and microfilaments that gives a eukaryotic cell its shape and its capacity to arrange its organelles and to move. Cytosol: the fluid portion of the cytoplasm, excluding organelles and other solids.
