Day 35 Osmosis

Name first and last

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

• food
• air
• water
• oxygen

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

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.

If a cell is placed in a hypotonic solution, the cell will _______.

• stay the same
• swell (get bigger)
• shrink (get smaller)

During osmosis

• water moves from high to low concentration
• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

Where will the water go?

• Into the cell
• Out of the cell
• Equally in & out - it's isotonic
• There is no water

A blood cell is placed into the jar, as seen. Where will the water go?

• Into the cell
• Out of the cell
• Equally in & out - it's isotonic
• The water is a lie

A person should never drink salty water because their cells would

• shrink
• expand
