Membrane Protein Quiz

Osmosis is the diffusion of water

    -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

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)
