Cell Transport EOC Review

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

Which process includes all of the others?

• passive transport

• facilitated diffusion

• diffusion across a membrane

• osmosis

When placed in a solution that is 30% water and 70% salt, what would happen to a cell that has a 70% water concentration?

• The cell will maintain its 70% water concentration and remain the same size

• The cell will lose water and shirnk to reach equilibrium with the environment

• The cell will take in water and well to reach equilibriumwith the environment.

• The cell will maintain to 70% water concentrationand swell to allow for some salt to enter the cell to reach equilibrium with the environment.

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.

The diffusion of water into or out of a cell is called

• solubility

• endocytosis

• selective transport

• osmosis

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.

• removes wastes

• reproduces

• creates energy

• maintains homeostasis

SC.912.L.14.2 Look at the cross section of a cell membrane of a eukaryotic cell. H+ ions are being pumped from

a low concentration to a high concentration.

How do you describe this type of transport across the cell membrane?

• Active transport

• Passive transport

• Facilitated Diffusion

• Co-transport

Which type of cell transport requires energy to move substances against their concentration gradient?

• Passive transport

• Facilitated diffusion

• Active transport

• Osmosis

What is the primary function of the cell membrane in transport?

• To provide structural support

• To control the movement of substances in and out of the cell

• To produce energy for the cell

• To store genetic information
