Information for cell lab:

For a copy of my handout: link.

Basic cell anatomy.

The first cells you will look at are cheek cells. Your slide should look somewhat like the picture below. The type of cell you are looking at is a squamous cell. 

How small are bacteria?

You will be viewing many of the cells that are shown below. You should review these cells so that you know what to expect in lab.

  Below are two views of stone cells.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The next image shows amyloplasts in potato cells.

 

What do amyloplasts store? Why are they purplish-black?

Below is a view of  chromoplasts from a red pepper.

The onion?

More of what you might see in lab about chloroplasts.

Specifically Elodea.

If you have (or are willing to download) Quicktime you can even see cytoplasmic streaming online!

Here is an electron microscopic view of something that should look familiar from lab, even though you have not yet viewed this particular organism.

A journey into the eukaryotic cell, a series. http://biology.about.com/library/weekly/aa031600a.htm

More detail than you will see, but how cool!

The picture below might help you in studying the plant cell.

Cells That Transport and Fight Bodily Invaders

White blood cells are properly termed leukocytes.There are five types of white blood cells: neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Neutrophils, eosinophils and basophils are granular leukocytes. You can probably guess why by looking at the picture of these cells below.

 

Below is a PP slide from http://medtech.umn.edu/Recruitment/sld038.htm

The slide shows the granulocytes as well as the other leukocytes, the lymphocytes and the monocytes.

Red blood cells, or erythrocytes, are shown below.

The picture is from http://www.wadsworth.org/chemheme/heme/microscope/pix/rbcs_nw.jpg

Note that there were plenty of RBCs in the pictures of WBCs shown above.

 

There's still more!

Another solid component of blood are the platelets.

Cells that are specialized for movement:

 

What is the appendage that allow sperm to move?
