3. 2
As water enters this plant cell structure, the cell becomes more turgid. This plant cell structure is the
A) vacuole. B) cytoplasm. C) cell wall. D) chloroplast.

4. A plant’s cell wall is composed of:3
A plant’s cell wall is composed of:
A) chitin B) cellulose C) lichen D) peptidoglycan

5. 4
Which image shows labeled organelles that are present ONLY in plant cells? A) B) D) C)

6. A) Diffusion B) Endocytosis C) Exocytosis D) Infiltration5
______ is the process of taking material into the cell by means of infoldings of the cell membrane.
A) Diffusion B) Endocytosis C) Exocytosis D) Infiltration

7. 6
The cell is taking in substances through membrane proteins, without any energy expenditure of its own. The substances naturally follow their concentration gradient. However, they must go through the protein channels, because they are too large to squeeze through the cell membrane. This process is called
A) osmosis. B) endocytosis. C) active transport. D) facilitated diffusion.

8. 7
_________ are responsible for the transport of large substances down a concentration gradient during facilitated diffusion.
A) Ionic pumps B) Ion channels or Ion carriers C) Carrier proteins or protein pumps D) Protein receptors

9. 8
Diffusion, osmosis, active transport All of these are methods by which a cell:
A) maintains homeostasis. B) creates energy. C) removes waste. D) reproduces.

10. 9
The cellular process in which materials are moved across a membrane from an area of low concentration to an area of high concentration is called
A) osmosis. B) simple diffusion. C) active transport. D) passive transport.

11. 10
An amoeba "eats" or engulfs a large amount of food through the process of
A) exocytosis. B) endoyctosis. C) passive transport. D) facilitated diffusion.
