Question

question 6
which of the following is the distinguishing feature of prokaryotic cells?
prokaryotic cells have a nucleus.
prokaryotic cells have mitochondria.
prokaryotic cells do not have a cell wall.
prokaryotic cells do not have a nucleus.

Explanation:

Prokaryotic cells lack a membrane - bound nucleus. Their genetic material is in the nucleoid region. Eukaryotic cells have a nucleus. Prokaryotic cells often have a cell wall (e.g., bacteria) and lack mitochondria (energy production occurs in the cell membrane - associated enzymes). So the key distinguishing feature among the options is that prokaryotic cells do not have a nucleus.

Answer:

Prokaryotic cells do not have a nucleus.
