a high water concentration = a low solute concentration
true
what is a compound ?
A compound is a substance formed by the chemical combination of two or more elements in fixed proportions
what is osmosis ?
Osmosis is the net movement of water molecules from a region of higher water concentration (dilute solution) to a region of lower concentration (concentrated solution) through a partially permeable membrane
what is the water potential gradient ?
a difference in water potential between two areas
true or false
Osmosis only involves the movement of water
True
True or false
Osmosis can take place without a membrane
Diffusion must take place across a membrane
False
Osmosis must take place across a membrane
Diffusion doesnt need a membrane in order to occur
