B1: Prokaryotic cells

The Differences 


Prokaryotic cells are different to eukaryotic cells such as animal and plants. An example of a prokaryotic cell is a bacteria cell.

A Prokaryotic cell or prokaryote is a cell that doesn’t have a nucleus.

Prokaryotic cells are smaller than eukaryotic cells.

They have a cell membrane, cytoplasm and ribosomes, like a eukaryotic cell.

However, they do not have a nucleus or mitochondrion.

This is the key difference.

Prokaryotic cells have rings of DNA that float around inside in the cell.

Some of these rings of DNA are called

This is very different to a eukaryote which has its DNA protected within a membrane called the nucleus.

Prokaryotic cells also have a cell wall which is similar but not the same as a plant cell wall.

Some prokaryotic cells have a slime layer outside the cell wall and include  which are like tails used to move the cell around.
