Read the following weblecture before chat: Cell Structure 2

Take notes on any questions you have, and be prepared to discuss the lecture in chat.

Study Activity

Rather than making you suffer through trying to figure out my drawings of cell structure, I figured it was time for a web tour, especially since some of the information and pictures available now are really amazing. As you study these, keep in mind the four fundamental parts of the cell and the organelles you will find in eukaryotic cells.

The best introductory level website on cell structure and variety is (in my opinion) Cells Alive! One of the problems with static pictures in you book is that it is hard to imagine the cells carrying out their individual tasks. After you click on the link above, explore the following locations on the site:

  1. Under "Interactive" on the left navigation menu, click on "Cell Models" and start the Animation.
  2. Select Plant Cell.
  3. Move around the cell to identify different structures.
  4. Look up the description of each structure by clicking on the links in the list at the bottom of the page. Return to the diagram by clicking on the red link in the bottom right corner of the picture area.
  5. Repeat your investigations for the animal cell.
