Selectively Permeable Membrane
Allows some materials to pass through but keeps other materials out
Concentration
Amount of substance in a given space
Diffusion
Movement of particles from an area of concentration to an area of lower concentratioin
Osmosis
Diffusion of water molecules through a selectively permeable membrane
Which best describes which directions molecules move during diffusion?
from an area of equilibrium to an area of high concentration
from an area of equilibrium to an area of low concentration
from an area of low concentration to an area of high concentration
from an area of high concentration to an area of low concentration
What is the process by which water diffuses across a selectively permeable membrane?
active transport
osmosis
simple diffusion
facilitated diffusion
Movement across the cell membrane that does not require energy from the cell is called
active transport
passive transport
mass transport
It is a type of passive transport which involves the movement of substances from a high concentration area to a low concentration area.
effusion
diffusion
concentration gradient
Osmosis is a process that requires energy to transport substances in and out of the cell.
True
False
When molecules are evenly distributed throughout the cell, they are said to be in
concentration gradient
equilibrium
homeostasis

A solution in which the concentration of dissolved substances is higher than the
concentration inside a cell is
