cell wall | skeleton for plant cells |
solution | solute + solvent |
saturated solution | max amount of solute dissolved |
homogenous | aka solution |
heterogeneous | mechanical mixture or suspension |
fluids | gases + liquids |
super saturated | increase temp to dissolve more |
semi permeable | allow some substances through only |
