 * Assessment statements** (IBO notes added to some point to clearly indicate what needs to be understood and what does not)
 * 2.2.1 || Draw and label a diagram of the ultrastructure of Escherichia coli (E. coli) as an example of a prokaryote. Include: cell wall, plasma membrane, cytoplasm, pili, flagella, ribosomes and nucleoid (region containing naked DNA). ||
 * 2.2.2 || Annotate the diagram from 2.2.1 with the functions of each named structure. ||
 * 2.2.3 || Identify structures from 2.2.1 in electron micrographs of E. coli. ||
 * 2.2.4 || State that prokaryotic cells divide by binary fission. ||

How well are your drawing skills progressing? Watch and draw your own example prokaryote media type="custom" key="24507910"

Essential Biology [|2.2 & 2.3 Prokaryotes & Eukaryotes] is an alternate set of notes encompassing both Prokaryotes and Eukaryotes
 * Workbooks and Worksheets**

[|McGraw-Hill online learning] has a very basic introduction to prokaryotes. Listen and read then move on to the other resources.
 * Presentations and tutorials**

Steven Taylor ([|i-Biology]) has a great presentation to view and take notes from before starting your notebook media type="custom" key="23679972"

Jason De Nys also has a very good presentation to use for note development media type="custom" key="24508048"

Use the [|Wiley Science] or the [|Shepard Software] tutorials to reinforce learning and augment your notes. [|Click Biology] is a straightforward non-interactive way to clarify and complete your notes.

The [|Shepard Software game] is a quick easy way to review prokaryotic cell structure. The [|biostuff tutorials] can be used later after note taking to check and reinforce knowledge as it directly reflecting the assessment statements. [|Pearson's Biocoach] can also be used to review your learning. Put your books away and use the quiz to check how much knowledge and understanding you have retained.

This video tutorial from Bozeman Science goes into greater depth than you need, but it's all useful detail and context media type="custom" key="24648434"

Bacteria can grow and divide potentially once every 20 minutes. This is a factor in making them a very successful type of organism. Cells Alive illustrates [|bacterial growth] very well. They also have a comprehensive [|gallery] of different cell images.
 * Useful links**

Learn about pathogens in a fun way by reading their [|microbe passports] - a great resource from [|Microbiology Online]

For the musically inclined how about learning about prokaryotes by rapping - [|lyrics found here]

Under Cell Labs you'll find links about the gram stain procedure. You should understand the procedure at the outline level. We will be carrying out a gram stain lab during this topic.
