Diffusion Osmosis

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

• Stay the same

• Shrink- get smaller

• Swell- get bigger

What happened to the CELL WALL and the CELL MEMBRANE in these plant cells?

• Both the CELL WALL and CELL MEMBRANE shrunk

• Only the CELL WALL shrunk, the CELL MEMBRANE stayed the same

• The CELL WALL stayed the same, only the CELL MEMBRANE shrunk

• Both the CELL WALL and CELL MEMBRANE stayed the same

Osmosis is specifically.....

• diffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentration

• the diffusion of particles from an area of high concentration to an area of low concentration

• diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration

• the diffusion of particles from an area of low concentration to an area of high concentration

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

• Osmosis

• Diffusion

• Active Transport

• Passive Transport

In which case would a cell most likely shrink?

• when placed in a solution containing a high salt concentration

• when placed in a isotonic solution

• when placed in a solution containing a low pH

• when placed in a solution containing distilled water

The picture below is an example of _________________ .

• osmosis

• isotonic

• diffusion

• active transport

Where will the water go?

• Into the cell

• Out of the cell

• Equally in & out - it's isotonic

• There is no water

Nemo and other ocean dwelling fish cannot survive in freshwater because......

• freshwater is hypertonic to Nemo's cells and will result in water leaving them causing the cells to shrink

• freshwater is hypotonic to Nemo's cells and will result in water leaving them causing the cells to shrink

• freshwater is hypertonic to Nemo's cells and will result in water entering them causing the cells to swell and burst

• freshwater is hypotonic to Nemo's cells and will result in water enter them causing the cells to swell and burst

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
