Cell Membrane & Transport

A balance that an organism maintains by regulating what goes into and out of the cell.

• Hypertonic
• Homeostasis
• Plasmolysis
• Hypotonic

The type of cellular transport that requires no energy.

• Active Transport
• Protein Pumps
• Passive Transport
• Endocytosis

The release of large particles, often waste materials from the inside of the cell to the outside of the cell.

• Osmosis
• Exocytosis
• Endocytosis
• Diffusion

What type of transport involves the movement of water from high to low concentrations?

• Diffusion
• Active Transport
• Facilitated Diffusion
• Osmosis

A cell with a 5% salt solution is placed into a beaker with a 10% salt solution.  This solution is considered to be _____ to the cell.

• Isotonic
• Hypertonic
• Hypotonic
• None of the Above

What happens to a plant cell that is placed into a hypotonic solution?

• It shrinks
• Plasmolysis
• It swells
• Cytolysis

Membrane Proteins

• A

• B

• D

• E

Which of the following is NOT true about diffusion?

• goes from high to low concentration

• uses cell energy

• is affected by sizes of molecules

• can move materials both ways through the cell membrane

Active transport differs from diffusion because

• active transport moves things into cells, while diffusion moves things out

• active transport moves small molecules, while diffusion moves large molecules

• active transport moves molecules from high to low concentration; diffusion only occurs from low to high concentration

• active transport moves things from low to high concentration; but diffusion moves molecules from high to low concentration

Which row in the chart best describes the active transport of molecule X through the cell membrane

• A

• B

• C

• D
