Question

question 34 of 50
which observation proves that a cell is a prokaryote?
a. it does not have a cytoskeleton.
b. it has a cell membrane.
c. it has cytosol inside the cell.
d. it does not have a nucleus.

Explanation:

Prokaryotic cells lack a nucleus. Eukaryotic cells have a nucleus. Both prokaryotic and eukaryotic cells have a cell membrane, cytosol, and some form of cytoskeleton (though prokaryotic cytoskeleton is simpler). So the key observation to identify a prokaryote is the absence of a nucleus.

Answer:

A. It does not have a nucleus
