3 2) All of the following are components of the modern cell theory except A) All living organisms are made up of one or more cells.

4 3) What is not characteristic of a prokaryotic cell? A) a plasma membrane B) a nuclear membrane C) ribosomes D) enzymes

5 4) Phospholipids A) are found in cell membranes B) are completely hydrophilic C) are completely hydrophobic D) are made on the ribosomes

6 5) The cells that line the intestine have highly folded plasma membranes on the absorptive surface of the intestine because A) this will increase volume, making the cells more efficient. B) this will increase surface area to volume ratio. C) these cells are most likely active in secretion. D) large amounts of plasma membrane will be needed for endocytosis.

7 6) All cells possess all the following components EXCEPT A) cytoplasm. B) genetic material. C) nuclear membrane. D) plasma cell membrane.

9 8) What is the meaning of the term "prokaryotic"? A) "false nucleus" B) "before the nucleus" C) "true nucleus" D) "small nucleus" E) "before the cell"

10 9) The cytoplasm of eukaryotic cells contains A) water. B) dissolved nutrients. C) organelles. D) all of the above

11 10) Only eukaryotic cells obtain energy and nutrients from the environment. True or false?

12 11) Flagellated bacteria A) can move internal organelles more efficiently than non-flagellated types. B) can attach to host cells more effectively because of the flagella. C) can move toward a favorable environment. D) divide more quickly non-flagellated types.
