What a cell really is...

Definitions:

1. The word prokaryote is etymologically composed of the

prefix pro- which means "before" and karyo which refers
to "nucleus", therefore, the prokaryotic cell is considered
prior to the cell that has a cell nucleus or eukaryotic cell.

2. The word eukaryote derives from the Greek eukayron,

composed of eu- (true), and karyon (nucleus), and means
'true nucleus'.

Definitions:

❖cell - is the smallest functional and structural unit of all

living organisms.

❖organism - is any living thing. All organisms are made

up of cells. Some organisms are just one cell.

❖organelle - a small body in the cytoplasm, which

performs a specific function within the cell.
