OSMOSIS/DIFFUSION & ACTIVE/PASSIVE TRANSPORT

An animal cell placed in a hyper-tonic (salty) solution will

• Swell up (get bigger)

• Shrink (get smaller)

• Stay the same

What is diffusion?

• molecules move everywhere

• no movement

• when molecules move from a high concentration to a low concentration

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.

The cell below is in a _________ solution.

• Hypotonic
• Hypertonic
• Isotonic

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

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

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

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

• Hypertonic
• Hypotonic
• Isotonic
• Cola
