Cell Membrane Quiz

Which feature of the cell membrane allows molecules such as oxygen and carbon dioxide to diffuse into and out of the cell?

• The production of protein

• The protein molecules are too large to diffuse out of the cells

• The cell membrane is made up of two layers of phospholipids.

• The cell membrane is anchored to the cytoplasm

What conclusion can be drawn from the diagram?

• Oxygen molecules are too large to pass through the cell membrane

• Water molecules are unable to move due to their size

• Protein molecules are stationary because they are exhausted

• The protein molecules cannot diffuse out of the cell due to their size.

• digestion

• synthesis

Sophia is conducting an experiment with a cell in water. Formulas of molecules that can move freely across the cell membrane are shown. Some molecules are located inside the cell and others are in the water outside the cell. Based on the distribution of these molecules, what would most likely happen after a period of time?

• The concentration of O2 would increase inside the cell.

• The concentration of CO2 will remain the same inside the cell.

• The concentration of O2 will remain the same outside the cell.

• The concentration of CO2 will decrease outside the cell.

A biologist placed a plant cell in a solution and observed it under a microscope. Initially, the cell appeared as shown in diagram X. After adding a 15% sugar solution, the cell appeared as shown in diagram Y. What caused the change in the cell's appearance?

• more sugar moving into the cell than out of the cell

• more sugar moving out of the cell than into the cell

• more water moving into the cell than out of the cell

• more water moving out of the cell than into the cell

What would be the expected outcome if iodine solution is added to the water in the beaker two hours after the potato slice was introduced?

• The iodine solution would turn blue-black if starch molecules diffused into the water in the beaker.

• The iodine solution would remain yellow-brown if no starch molecules diffused into the water in the beaker.

• The iodine solution would turn red if starch molecules were not present in the water in the beaker.

• The iodine solution would remain colorless if starch molecules were present in the water in the beaker.

What can be inferred about solution D?

• The concentration of dissolved salt in the solution is equal to the concentration in the cells.

• The concentration of dissolved salt in the solution is less than the concentration in the cells.

• The concentration of water in the solution is less than the concentration in the cells.

• The concentration of water in the solution is greater than the concentration in the cells.
