LT 2.4 Cell Transport Quiz

A and B in the diagram below represent two different slide preparations of elodea leaves.  Elodea is a plant found in freshwater streams and ponds. Elodea cells normally contain 1% salt. The salt solution concentrations for A was 1% and B was 6%.

After the slides were prepared, a student using a compound light microscope to observe the cells in leaves A and B would most likely see:

A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. Which of the following has occurred?

The cell membrane controls movement of materials into and out of the cell. A type of particle is moving from high concentration to low concentration and is using a carrier protein. How would you describe this type of movement across the membrane?

Look at the cross section of a cell membrane of a eukaryotic cell in which H+ ions are being pumped across the cell membrane.

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

Each shows a beaker containing a solution with various sugar concentrations. Small and permeable bags are placed in each of the beakers, each bag contains a 25% sugar solution. The bags remained in the beakers for 20 minutes before the mass of each bag was measured. Which bag should show the greatest change in mass?

The diagram below represents a specialized cell located in the root of a plant.  The arrows in the diagram indicate the movement of molecules of oxygen and water into the cell. Which row in the chart correctly identifies the process responsible for the movement of each type of molecule represented in the diagram?

The illustration shows which process taking place?

Which diagram below represents the use of a protein pump?

A substance moving through a protein from high concentration to low concentration is _____________________________; whereas a substance moving through a protein from low concentration to high concentration is ________________. The biggest difference is the first ________________ while the second ______________.
