Chapter 3, Section 4: The Cell in Its Environment

California Science Standard: S 7.1.a

• In prior sections students have learned that the cell membrane controls the movement of materials into and out of a cell. Now, they will see how this control occurs.


• Students know that cells function similarly in all living organisms.

Text Key Concepts/Objectives:

3.4.1 - Describe how most small molecules cross the cell membrane
3.4.2 - Explain why osmosis is important to cells
3.4.3 - Tell the difference between passive transport and active transport.
