Requires the cell to use energy

Movement of particles against the concentration gradient from an area of higher concentration to an area of lower concentration

Chose the three types of passive transport

Choose the three types of active transport

Movement of particles with the concentration gradient, from an area of higher concentration to an area of lower concentration

The transport of materials across the cell membrane with the aid of a carrier (transport) protein

The diffusion of water across a selectively permeable membrane

Concentration is lower in the solution outside the cell than inside, meaning there is more water on the outside the cell than inside. The cell will swell and possibly burst.

Concentration is higher in the solution outside the cell than inside, meaning there is less water on the outside the cell than inside. The cell will shrink and possibly dehydrate.

Concentration is the same in the solution outside the cell as inside, meaning there are equal amount of water on each side of the cell membrane. Water will not move because it is at equilibrium.

Cell membrane surrounds particles and takes in from outside environment.

Cell releases materials from the vesicle or vacuole to outside environment to get rid of wastes.

Taking in liquids through endocytosis. Cell "drinking"

Taking in solids through endocytosis. Cell "eating"
