Understanding Osmosis and Solution Types

Osmosis: Diffusion of water across a semipermeable membrane (plasma membrane),

passive process (no energy required), specifically for water (goes from high to low concentration)

It is like diffusion, except it is hard to quantify the concentration of water (solvent)

so we talk abt the concentration of material dissolved in water (solute concentration -

like salt) Water moves w/ its gradient but moves from low solute concentration gradient

to high solute concentration gradient (bc if low solute than there is a high water concentration

and then the other part must have a high solute concentration and low water concentration, water still moves

hi-low) Hypotonic solutions (low solute, high water concentration) More solute and
