Dec 9 and Dec 10

Objective:
The scholars will perform an EGG-SPERIMENT in order to identify what osmosis is.


Warm Up:
1. The diffusion of water across a selectively permeable membrane is called
F osmotic pressure.
G osmosis.
H facilitated diffusion.
J active transport.

2. An animal cell that is surrounded by distilled water will burst because
A water will move into the cell.
B water will move out of the cell.
C solutes will move into the cell.
D solutes will move out of the cell.

3. Which of the following is NOT an example of active transport?
I. Facilitated Diffusion
II. Osmosis
III. Diffusion
F I only
G II only
H II and III only
J I, II, and III

4. Juan observes a cell under the microscope. He identifies it as a green plant cell and not a human cheek cell because of the presence of a
A nucleus
B cell wall
C cell membrane
D mitochondrion

Use the information below to answer Numbers 5 and 6.
A student is studying the growth of yeast, a single-celled eukaryotic organism that is used to make bread. She
adds yeast cells to a flask containing a sugar solution and then places the flask in an incubator at 300C. After 36
hours, he observes the flask to determine whether the yeast cells have grown.

5. Which of these is directly involved in transporting nutrients from the sugar solution into the yeast?
F the cell membrane
G the nucleus
H the vacuoles
J the ribosomes

6. Which part of the yeast cell converts the nutrients in the sugar solution into energy?
A the cell membrane
B the nucleus
C the mitochondria
D the ribosomes
