Below are several questions asking you to think about how a variety of substances transfer into or out of the cell membrane. Remember to consider the difference between active and passive transport as you answer these questions.
Question 1
1.
What kind of transport is depicted in the image? Name at least one reason how you know it is that kind of transport.
Question 2
2.
Question 3
3.
Label the types of solutions below.
Other Answer Choices:
Hypertonic
Hypotonic
Isotonic
Question 4
4.
Question 5
5.
Draw a picture of a channel protein in the cell membrane and include a particle passing through the channel. Artistic skill will NOT be taken into account while grading. As long as you include a portion of the cell membrane, a channel protein, and a particle undergoing transport, you will get full credit.
What happens to a cell in a hypertonic solution?
Nothing happens. The net flow of water in and out of the cell are equal.
Water flows out of the cell via osmosis and the cell shrivels.
Water flows into the cell via osmosis and the cell bursts.
Large molecules can diffuse through the cell membrane.
