diffusion and osmosis quiz redo

Passive transport requires energy to move molecules across the cell membrane.

False

Diffusion is a type of passive transport

True

How is facilitated diffusion different from simple diffusion?

Proteins are used to move molecules across the membrane.

Diffusion is the movement of molecules from __________ to _____________ concentration.

High, low

Osmosis is the movement of __________ molecules across a semi-permeable membrane.

Solvent

Moving molecules against their concentration gradient requires the use of energy. Which type of transport is this?

Active

Which statement does not describe this image below?

Osmosis is occurring

Describe how would you make lemonade from a powder mixture using these terms: solute, solvent, and solution.

First, you take the cup and put your solvent (water) and put that in the cup.

Second, you take your solute (Lemonade powder mixture) and put it into your solvent (Water) then you’ll have your solution. (Lemonade)

One similarity and difference of osmosis and diffusion.

Similarity: Both are forms of passive transport not requiring ATP.

Difference: Osmosis needs a semi-permeable membrane to work, while diffusion can work with or without one.

Which one is hypertonic, isotonic, and hypotonic.

1. Hypertonic

2. Isotonic

3. Hypotonic

If a blood cell is in a hypertonic environment, what would you expect to happen to the cell?

It will shrink because water is moving out the blood cell through osmosis.
