-When water moves from an area of high concentration to low concentration
Some words we need to know:
-Solvent-Usually water-the substance there is more of. the liquid doing the dissolving.
-Solute-The other substance in the mixture of the solvent and the solute. Usually the stuff mixed in with water
-Hypertonic- having less water (More pressure)
-Hypotonic- having more water (Less pressure)
-Isotonic- having an even amount (Same pressure)
-Equilibrium- having same pressure- isotonic
As an extra resource here is the Khan Academy Video on Osmosis
Watch this intro to osmosis video. Take notes. Make sure you know the difference between hypotonic, hypertonic, and isotonic.
Watch this video on why Honey does not expire. Take notes because I might ask you a test question about food and osmosis.
This is an optional video if you want to know more about why honey does not expire.
For your quiz be able to label a jar as hypertonic, hypotonic, isotonic, and be able to say which direction the water will travel.
-Active Transport (Requires energy)
-Endocytosis (When cells engulf things)
-Pinocytosis (When a cell engulfs a large drop of water)
-Phagocytosis (When a cell eats)
-Exocytosis (When a cell sends things outside)
