Solutes move with the concentration gradient, therefore no energy is used. 

• Passive Transport

• Active Transport

Passive transport is called "passive" because it occurs WITHOUT

• cause.

• energy.

• a concentration gradient.

• a cell wall.

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)

• Active uses ATP (energy) and passive does not need energy

• Active stores transport proteins and passive releases 

• Active uses hormones and passive does not 

What process occurs when WATER diffuses across a membrane?

• endocytosis

• mitosis

• osmosis

• nuclear fission 

Which way will the water molecules move during osmosis Hint those  mickey mouse molecules are water not solutes?

• Out of the cell, so the cell shrinks.

• Out of the cell, so the cell swells.

• Into the cell, so the cell shrinks.

• Into the cell, so the cell swells.
