Back 1

Hint 1

This word comes from the latin words "to pass through"

Front 2

Hint 3

Back 4

osmosis

Hint 4

_____ is important to cells because cells cannot function properly without adequate water.

Front 5

The movement of materials through a cell membrane without using energy is called _______.

Back 5

Hint 5

Your body requires energy to do this

Front 6

______ is the movement of materials through a cell membrane using energy.

Back 6
