Red blood cells burst when placed in pure water. Draw a model explaining the phenomenon (its osmosis). Label semipermeable membrane, solute concentration, and movement of water in your model. can someone explain what it would look like it words? thank you!

Draw the semi-permeable membrane (the two layers of spoon-looking things), draw a bunch of shapes representing salt or something on one side with a few other shapes representing water, then do the opposite on the other side of the membrane.

Explanation:

Osmosis is basically the idea that the membrane tries to keep the concentration of water and whatever is dissolved in the water equal on either side. So if the inside of a cell has a bunch of salt and a little water, and the outside has a little salt but lots of water, a bunch of the water is going to rush into the cell to try to balance out the concentrations. But since cells can't stretch out forever, eventually it gets so full of water it can't fit anymore, and bursts.
