Answer:
The classification of organisms as either a prokaryote or a eukaryote is based on the structure of the organism's cell nucleus
Explanation:
The etymology of the word 'karyote' in both 'prokaryote' and 'eukaryote', is derived from a Greek word that explains the nucleus.
An organism having a true nucleus (i.e a nucleus surrounded by a nuclear membrane) in its cell(s), is classified as a eukaryote.
'Eu' in the word 'eukaryote', is derived from a Greek word that means 'true'.
A prokaryote is an organism that lacks a definite nucleus, hence, having its genetic materials suspended freely in the cyoplasm without a special nuclear membrane enclosing it, aside from its plasma membrane.
