Transport Review

Both side of a selectively- permeable membrane are equal. The sides are ______.

• isotonic
• hypertonic
• hypotonic

Osmosis is the diffusion of _____ across a selectively permeable membrane.

• food
• air
• water
• oxygen

During diffusion

• substances (things) moves from high to low concentration
• water moves when energy is used
• large or oddly shaped molecules move across a cell membrane
• water moves from high to low concentration

 In the given scenario what will happen?  An egg with a dissolved shell is placed in pure water for 48 hours.

• Water will move in and out of the cell equally, and the cell with neither shrink nor swell.
• The egg will gain water and swell.
• The egg will lose water and shrink.

 An animal cell placed in a hypertonic (salty) solution will

• Stay the same
• Shrink- get smaller
• Swell- get bigger

Ideally, your cells should be in a(n) _______ solution

• isotonic
• hypertonic
• hypotonic
• isometric

The picture  is an example of _________________.

• isotonic
• diffusion
• osmosis
• active transport

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of ___________.

• osmosis
• equilibrium
• diffusion
• hypertonic

In a solution, salt is considered the _______.

• solvent
• solute
• solution

In this given scenario, corn syrup is hypertonic to an egg with a dissolved shell. What will happen to the egg when it is place in corn syrup?

• It will stay the same.
• It will swell- get bigger.
• It will shrink- get smaller.
