Lesson details
Key learning points
- Bacteria are prokaryotic organisms.
- Common features of prokaryotic cells include the cell membrane, cytoplasm and cell wall.
- Prokaryotic cells do not have a nucleus; they store their genetic material in the cell cytoplasm.
- The genetic material is stored in one looped chromosome.
- Extra genetic material can be stored in small loops called plasmids.
Common misconception
All bacterial cells looks like the bacterial cell model.
Bacteria can come in different shapes and sizes, this will be outlined within the slide deck.
Keywords
Prokaryotic - A type of cell with no membrane bound nucleus; DNA is free floating in the cytoplasm.
Plasmid - Small ring of DNA found in the cytoplasm of prokaryotic cells.
Binary fission - The form of cell division that bacteria use to replicate.
Eukaryotic - A type of cell that contains a membrane bound nucleus; the DNA is usually found inside.
