Quick10Q: Diffusion & Osmosis

You are a farmer growing crops. The concentration of your potatoes are 0.35M and you are advised to water your plants with a 0.35M saline solution to provide nutrients. What happens to the plant cells?

• Cells are normal since this is an isotonic solution.

• Cells become flaccid since this is an isotonic solution.

• Cell become plasmolyzed since this is an isotonic solution.

You are a doctor. A patient comes in dehydrated. What type of solution would be best to place into their IV?

• A hypotonic solution to allow the cells to rehydrate.

• A slightly hypertonic solution to allow the cells to rehydrate.

• An isotonic solution to increase fluid in the body without causing harm to the cells.

• An isotonic solution to decrease fluid in the body without causing harm to the cells.

Which of the following describes an appropriate water movement pathway?

• hypotonic solution to hypertonic solution

• hypertonic solution to hypotonic solution

• hypertonic solution to isotonic solution

• isotonic solution to hypotonic solution

What is the difference between the molecule transported in facilitated diffusion versus simple diffusion?

• facilitated diffusion involves nonpolar solute transport through a membrane protein

• simple diffusion involves nonpolar solute transport through a membrane protein

• facilitated diffusion involves polar solute transport through a membrane protein

• simple diffusion involved polar solute transport through a membrane protein

Which of the following describes the difference between passive and active transport?

• passive transport involves moving solutes against the concentration gradient using ATP.

• active transport involves moving solutes against the concentration gradient using ATP.

• passive transport involves moving solutes with the concentration gradient using ATP.

• active transport involves moving solutes with the concentration gradient using ATP.

Which of the following describes the difference between channel and carrier transport proteins?

• channel proteins bind to solute to shuttle the solute across the membrane

• channel proteins provide a nonpolar channel through the membrane

• carrier proteins bind to solute to shuttle the solute across the membrane

• carrier proteins provide a nonpolar channel through the membrane

Describe what would happen if you placed an animal cell in 1.0 M solution.

• The cell would lyse

• The cell would be flaccid

• The cell would shrivel

• The cell would be normal

Describe what would happen if you placed a plant cell in a 0.0 M solution.

• The cell would lyse

• The cell would be turgid

• The cell would plasmolyze

• The cell would be flaccid

What organelle found in a plant cell provides the plant cell with turgid pressure?

What property of the plasma membrane allows for oxygen and carbon dioxide to diffuse by simple diffusion?

• Phospholipids are nonpolar allowing for small, nonpolar substances to dissolve.

• Phospholipids are polar allowing for small, polar substances to dissolve.

• Phospholipids are amphipathic allowing for a nonpolar interior for nonpolar substances to diffuse.

• Phospholipids are amphipathic allowing for polar interior for polar substances to diffuse.
