Bacteria are single-celled prokaryotic organisms. The diagram below shows the detailed structure of a bacterium with key components labelled A to G.
The table below lists the physiological functions of specific structures within the bacterial cell. Complete the table by writing the letter (A to G) of the part that performs each function.
| Function | Letter of part |
|---|---|
| the site of translation during protein synthesis | |
| a tail-like structure that rotates to provide motility |
The table below lists several biological statements. Put a tick (✓\checkmark✓) in the boxes next to the two statements that are correct for bacteria.
| Statement | Tick |
|---|---|
| contain 80S ribosomes in the cytoplasm | |
| possess a cell wall made of peptidoglycan (murein) | |
| undergo mitosis to replicate and divide | |
| can be genetically engineered to produce insulin for medical use | |
| contain membrane-bound organelles such as endoplasmic reticulum |
