Cell Transport - Mrs. Xavier

Review of Cell Transport Name: _______KEY____________________

1. Directions: Complete the concept map below to use as a study guide to help you remember the differences between passive transport and active transport.  You can begin with the phrase “transport through membranes.”

Below are words you will use.

 facilitated diffusion     active transport   osmosis     exocytosis     endocytosis    pump   

without energy           simple diffusion

     Osmosis                               

        Endocytosis               Pumps                                                                                               Fa

Simple diffusion         Fac. diffusion

Exocytosis

Where on this concept map would you add Phagocytosis and Pinocytosis? Please add them where they belong. 

Underneath active transport/ endocytosis

What is the difference between the two? ___

_Phagocytosis is cell eating (solid particles )Pinocytosis is cell drinking (small molecules or ions)

MEMBRANE STRUCTURE and  TRANSPORT REVIEW

Correctly and identify the name for each part of the cell membrane.

Match the cell membrane structure or its function with the correct letter from the cell membrane diagram.

Osmosis and Tonicity

Use arrows to show the direction of water movement into or out of each cell.  

 OUT NO                                                              IN

Match the 

Match each  description with the osmotic condition:

Complete the table by checking the correct column for each statement:

Transport Requiring Energy

What type of transport is represented by the picture? __Active/ Pump

What energy is being used? ___ATP energy

In which direction (concentration gradient), is the movement occurring? 

Low to high

Against the concentration gradient

Match the term with its correct description:

1. energy

2. active transport

3. facilitated diffusion

4. channel protein

5. carrier protein

6. passive transport
   

D_ Transport protein that provides a tube-like opening in the plasma membrane through which particles can diffuse

A_ Is used during active transport but not passive transport

F_ Particle movement from an area of higher concentration to an area of lower concentration

C_ A form of passive transport that uses transport proteins

B_ Particle movement from an area of lower concentration to an area of higher concentration

E_ Transport protein that changes shape when a particle binds with it

Write the letter of the definition next to the correct vocabulary word.
