Answers
Answer:
(a) Cilia or flagella project as whip-like structures from the cell surface; a cross-section through a flagellum reveals the arrangement of outer doublet (arrowheads) and central pair (asterisk) microtubules in a motile axoneme. (b) Motile cilia lining the human respiratory tract. (c) Human sperm. (d) Chlamydomonas sp., a biflagellate green alga and principal model system for many studies of flagellar biology. (e) The voracious predator Didinium sp. devouring its favored prey Paramecium; note the two bands of cilia that support the motility of this ciliate. (f, g) In other ciliates (e.g., Paramecium caudatum), cilia are arrayed across the cell surface. Cilia are also present along the oral groove and are used to waft food into the oral cavity (arrowhead). In the image shown in panel (g), the ciliates are on a mat of false-colored filamentous Oscillatoria cyanobacteria. (h) The intestinal parasite and possible ancient eukaryote Giardia lamblia; its basal bodies are located deep in the cytoplasm, and the axonemes of eight flagella traverse through the cytosol before emerging from different exit points on the cell surface. (i) The uniflagellate human sleeping sickness parasite, Trypanosoma brucei, shown among red blood cells.
