Cell Membranes
Selectively permeable Allow only some things to enter and leave.

Passive Transport
Movement of material through the membrane without using energy.

Types of Passive Transport
Diffusion Random movement of particles from areas
of more to areas of less. Equilibrium – equal particles in each area.

Types of Passive Transport
Osmosis The diffusion of water through the cell
membrane. Example: Plants

Types of Passive Transport
Facilitated Diffusion Movement of materials through a transport
protein located in the membrane.

Active Transport
Moving materials through a cell membrane with the use of energy. Requires transport proteins.

Movement of Very Large Particles
Endocytosis Cell membrane surrounds the particle. Section of the membrane pinches off to
form a vesicle.

Movement of Very Large Particles
Exocytosis Opposite process as endocytosis. Contents of the vesicle are released
outside the membrane.
