The following diagram is of a typical membrane. In your own words explain:

 

 

Why the two layers of phospholipids in a single membrane make such a stable structure:

________________________________________________________________________________________________________________________________________________

 

Why most molecules cannot cross the membrane:

________________________________________________________________________________________________________________________________________________

 

 

Identify the structure above.  What kinds of cells have this structure?  What is its function and how is this function performed? What is the function of the nucleolus?  How do molecules get in and out of the nucleus?

 

“Double Barrel” structures above are called centrioles.  What kinds of cells have this structure?  What is its function and how is this function performed?

 

 

The diagram above is part of a much larger structure you must identify.  What kinds of cells have this structure?  What is its function and how is this function performed?

 

 

Identify the structure above.  What kinds of cells have this structure?  What is its function and how is this function performed?

                                                                                                                                                 

 

The top half of the bottom diagram is Golgi.  What is the bottom half of the diagram?

Identify the structure above.  What kinds of cells have Golgi?  What is its function and how is this function performed?

 

Name the special organelle involved in digestion made by Golgi? 

What kinds of cells have these organelles?

 

 

Identify the structure above.  What kinds of cells have this structure?  What is its function and how is this function performed?

 

 

The above is an enlargement of a structure already shown in a diagram on this worksheet.

 

Where have you already seen ribosomes?  What kinds of cells have this structure?  What is its function and how is this function performed?

 

 

What two kinds of structures make up the cytoskeleton? 

What are the two different functions of the cytoskeleton?

 

 

The diagram above is a cross section of a very long stucture connected to the cytoskeleton.  Identify the structure above.  What kinds of cells have this structure?  What is its function and how is this function performed?

 

 

Identify the structure above.  What kinds of cells have this structure?  What is its function and how is this function performed?

 

Label each structure in the following diagram:
