Cell structure and diversity

Take some time to click through this site to learn more about cells and their structures.   Here is another good place to learn about cells.   Look through each site and then leave me a comment as to which of them you preferred and WHY

If you find any other sites on this topic that you think would help your classmates learn, please include them in the comments too.

Here is a link to a quiz that you can use to check your understanding of cells.  It is brief – my advice is that you study the structure of prokaryotic and eukaryotic cells, and their functions, and their differences, then see how you go on the quiz.  The answers are on there too, so you can self-assess.

Quiz – cell parts and their functions

What do all cells have in common?

Why do cells differentiate?  Within the same organism, there are differences between cells – why is this?

Here’s what you need to do:-

  1. In your groups, make a list of all the different types of cells you can think of (eg, red blood cell, leaf cell)
  2. Each student chooses ONE cell type to research.  Draw the basic structure, state its function, describe why it is unique, and where it is found.
  3. Share your findings with your group.
  4. Discuss the similarities and differences between the cells you described.  Are cells more alike or more different from one another?  Are some cells more complex than others?  Which ones? 
  5. Try to explain why cells have these similarities and differences.

Watch this brainpop video on cells to introduce the topic.  For more detail on cell structures, watch this.   For comparisons on plant and animal cells and cell specialization watch this.

You need to be able to do the following:-

  • Draw and label a diagram of a simplified animal cell.
  • Draw and label a diagram of a simplified plant cell.
  • State the functions for each of the labels on the above diagrams.
  • Compare animal and plant cell structure and relate to their functions.
  • Understand that cells are differentiated for their functions, and give some examples of these specializations.

E Coli by hukuzatuna on flickr

The syllabus guide for Topic 2 is here: Topic 2 – syllabus outline

You need to be able to draw, label and annotate a diagram of E.Coli (a prokaryote) and a liver cell (a eukaryote).  In addition you should be able to recognize these structures on an electron micrograph like the one pictured. 

You will also have to compare prokarotes and eukaryotes, and compare plant and animal cells.

Here are a couple of great presentations to help you achieve these tasks, and I’ll be giving you several handouts to practice with.  We’ll be getting the light microscopes out for a play too, as well as making our own slides to view.  Presentation on prokaryotesPresentation on eukaryotes.
