Osmosis, Diffusion, and Active Transport

The process of osmosis is best illustrated by the movement of:

• water into root hair cells

• oxygen into red blood cells

• carbon dioxide through stomates

• glucose through phloem

Why did the gummy bear bloat when placed in water?

• osmosis of water into bear

• diffusion of sugar out of bear

• active transport of water into bear

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

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, 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

The girl sitting two rows ahead of you put on too much perfume this morning. Is this diffusion, osmosis or active transport?

• diffusion

• osmosis

• active transport
