Lesson Details
Key learning points
- Eukaryotic cells store their genetic material in a nucleus and have membrane bound sub-cellular structures.
- Eukaryotic organisms can be unicellular or multicellular.
- Examples of eukaryotic and prokaryotic organisms.
- Prokaryotic cells do not have membrane bound sub-cellular structures including a nucleus; DNA is floating in cytoplasm.
- Prokaryotic organisms are unicellular.
Common misconception
All eukaryotic cells are multicellular.
Addressed within the slides to specifically mention that some eukaryotic organisms are unicellular.
Keywords
Eukaryotic - Eukaryotic cells contain a membrane bound nucleus; this contains the DNA.
Multicellular - Organisms that are made up of more than one cell are multicellular.
Prokaryotic - Prokaryotic cells have no membrane bound nucleus; DNA is free floating in the cytoplasm.
Unicellular - An organism that consists of only one cell is unicellular.
