Diffusion and Osmosis

How do the particles move in diffusion?

• From a region of low concentration to a region of high concentration

• From a region of high concentration to a region of low concentration

• From a region of low concentration to a region of low concentration

• From a region of high concentration to a region of high concentration

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

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.

What is the diffusion of water only across a cell or semi-permeable membrane?

• Osmosis
• Diffusion
• Active Transport
• Passive Transport

Where will the water go?

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

In the cell pictured, which way would water move?

• Into the cell, causing the cell to swell

• Out of the cell, causing the cell to shrink

• In and out of the cell equally, keeping the shape the same

In the cell pictured, where would water move? 

• Into the cell, causing it to swell

• Out of the cell, causing it to shrink

• In and out of the cell equally, causing the shape to stay the same

In the cell pictured, which way would water move?

• Into the cell, causing the cell to swell

• Out of the cell, causing the cell to shrink

• In and out of the cell equally, keeping the shape the same
