1 Chapter 2 Section 3 Life Science

2 THE Cell Membrane Cells survive by allowing some items to pass through the cell membrane. ***Cell Membrane is “Selectively Permeable” Selectively Permeable- “selects” certain materials to go in and out of the cell membrane.

3 2 types of Movement through the Cell Membrane:
Passive Transport- does not require energy to pass through cell membrane Active Transport- requires energy

4 FOCUS: Passive Transport
The movement of substances through the cell membrane without the input of energy is called Passive Transport. There are three types of Passive Transport that can occur.

5 1st Type of Passive Transport
Diffusion- movement of “materials” from an area of high concentration to low concentration. Examples- Febreeze Oxygen and Carbon Dioxide molecules moving across membrane

6 EQUILIBRIUM Ending Result- Equilibrium
This is when it’s EQUAL on both sides BALANCED!!!

7 2nd Type of Passive Transport
Osmosis- movement of water from an area of high concentration to low concentration Examples- Wilting Plant (needs H2O)

8 EQUILIBRIUM Ending Result... Equilibrium
This is when it’s EQUAL on both sides BALANCE!!!

Cell Transport The movement of molecules can be either passive (no energy) or active (needs energy) depending upon the membrane structure and concentration.
