1.1.1 Eukaryotes and Prokaryotes

What are the two main types of cells?

The two main types of cells are prokaryotic and eukaryotic.

What are eukaryotic cells?

Eukaryotic cells are cells that contain a nucleus and membrane-bound organelles.

Give two examples of eukaryotic cells.

Animal cells and plant cells are eukaryotic cells.

What structures do eukaryotic cells have?

Eukaryotic cells have a cell membrane, cytoplasm, and a nucleus containing DNA.

What are prokaryotic cells?

Prokaryotic cells are cells that do not contain a nucleus; their genetic material is stored in the cytoplasm.

Give one example of a prokaryotic cell.

A bacterial cell is an example of a prokaryotic cell.

What structures do bacterial cells have?

Bacterial cells have a cell wall, a cell membrane, cytoplasm, and a single circular strand of DNA and plasmids.

What are plasmids?

Plasmids are small rings of DNA found in the cytoplasm of bacterial cells that can replicate independently.

What is the function of organelles?

Organelles are specialised structures in a cell that carry out different functions.
