Why do molecules move during passive transport?

• To see the world

• To achieve hypertonicity

Which type of molecule moves easily across the cell membrane?

• Small particles like oxygen and water

• Large molecules like sugar

• Medium size proteins

• Other cells

Why is the cell membrane semi-permeable?

• No substances may enter

• All substances may enter
