Draw and label a diagram of the ultrastructure of Escherichia coli (E. coli) as an example of a prokaryote.

Annotate the diagram of the ultrastructure of E. coli with the functions of each named structure.
Plasmids: Very small, circular pieces of DNA that can be transferred from one bacteria to another during conjugation. Can contain beneficial genes, such as those for antibiotic resistance. Used in creating recombinant DNA/genetic engineering.
Conjugation: The transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells.
Identify structures from electron micrographs of E. coli.
State that prokaryotic cells divide by binary fission.
IB Biology Drawing rules: “All Drawings” 1. Are done with a sharp pencil line on white, unlined paper. 2. Occupy at least half a page, centered on the page. 3. Include labels written off straight, horizontal lines to the right of the side of the drawing. The labels should form a vertical list. 4. Are accurate: draw what you see as you see it, not what you imagine should be there. 5. Include a title that states what has been drawn and what lens power it was drawn under; the title must be informative, centered, and larger than other text. 6. Have a scale that indicates how many times larger the drawing is compared to life size and a scale line that indicates relative size.”
