Why is the cell membrane a "semi-permeable" membrane?

• It allows small and non polar molecules to pass in

• It allows large and polar molecules to pass in

• It allows large and non polar molecules to pass in

• allows small and polar molecules to pass in

Since cell membrane is semi-permeable, how would other substances like ions able to enter the cell?

• Using emulsifying proteins

• Using transport proteins

• Using ATP of the cell

• Using chemical reactions.

In _____ _______, molecules move from lower to higher concentration, and requires energy in the form of ATP. It also requires transport protein.

• Active transport

• Passive transport

• Endocytosis

• Exocytosis

The movement of substances across the membrane without the addition of energy.

• Active transport

• Passive transport

• Endocytosis

• Exocytosis
