Osmosis

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

 If the volume of a cell increases when it is placed in a solution, that solution is said to be __________ to the cell

•  hypertonic
• subatomic
•  isotonic
•  hypotonic 

Which way will the water molecules move during osmosis?

• Out of the cell, so the cell shrinks.
• Out of the cell, so the cell swells.
• Into the cell, so the cell shrinks.
• Into the cell, so the cell swells.

Osmosis is a form of ______________. 

• Passive Transport
• Active Transport

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

• isotonic
• hypertonic
• hypotonic
• isometric

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.

If you looked at red blood cells under a microscope and saw the blood cells exploded, what would you say happened?

• The cells were placed in a hypotonic solution.
• the solution was isotonic.
• The solution was hypertonic.

• hypertonic-
• hypotonic
• isotonic

If the dots represent sugar, what direction will water flow?
