The Movement of Water by Osmosis Chapter 4 The Movement of Water by Osmosis

Diffusion and Osmosis Solutes are: _____________________________________________ This movement of molecules is called:________________________

Diffusion of water is called: _____________________

Ocean Water contains solutes. Which solute would be considered the main solute? _____________ The results is that too much water leaves animals’ bodies. What effect would this have on the animal’s cells. ________________ These organisms must find ways to deal with this diffusion and osmosis.

Regulation of Solute/Water Balance Osmoconformers - Internal concentration varies as the salinity in the water around them changes - Most can tolerate a (very narrow / large) range of salinity Give 4 Examples: 1)_______________________________ 2)_______________________________ 3)_______________________________ 4)_______________________________

Regulation of Solute/Water Balance Osmoregulators - Control their internal concentrations - Most can tolerate a (very narrow / wider range) range of salinity Give 4 Examples: 1)_______________________________ 2)_______________________________ 3)_______________________________ 4)_______________________________
