EOC Cell Transport

Which will most likely happen if a freshwater plant cell is placed in a beaker of salt water for an hour?

• It will swell and burst.

• It will lose water and shrink.

• It will reach a state of equilibrium.

• It will use energy and pump extra salt out of the cell.

What would happen to blood cells if they were placed in pure water?

• The cells would burst because water would enter the cells.

• The cells would burst because water would exit the cells.

• The cells would shrink due to water exiting the cells

• The cells would stay the same size.

Which of the following is considered to be passive transport?

• facilitated diffusion

• sodium potassium pump

• endocytosis

• exocytosis

In the process of diffusion, molecules move:

• from areas of high concentration to areas of low concentration

• back and forth equally

• not at all

Shira is analyzing samples of red blood cells using a microscope. Her observations are shown in the image. Shira observes that the shape of Cell A appears normal, while Cell B appears swollen and Cell C is shrunken. The shrinking of cell C indicates what has occurred?

• an anaerobic environment outside of the cell

• lower solute concentration outside of the cell than inside

• more oxygen inside the cell than what can be utilized

• higher solute concentration outside the cell than inside
