How does the cell membrane recognize chemical signals?

• By producing signals

• By recognizing chemical signals (messages) which will trigger the cell to react in a particular way

• By storing signals

• By destroying signals

What does it mean when a cell membrane is selectively permeable?

• All molecules can pass through

• No molecules can pass through

• Some molecules can pass through, and some cannot

• It allows only water to pass through.

What is the cell membrane primarily made up of?
