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.

There are sub-cellular structures that have not been mentioned within the lesson that students may be familiar with. It might be good to remind students that they are present, but that they are not membrane bound or linked to understanding the difference between eukaryotic and prokaryotic cells.
