Answer:
d. whether or not the cell is partitioned by internal membranes.
Step-by-step explanation:
The prokaryotic cells are those which do not have a defined or definite nucleus because the nucleus is not bounded by the nuclear membrane. This type of nucleus is called nucleon. The prokaryotic cell also does not have membrane-bound cell organelles. Thus, the prokaryotic cell is not partitioned by internal membranes.
Whereas, a eukaryotic cell has a well-defined or definite nucleus and membrane-bound organelles such as mitochondria, chloroplasts, Golgi apparatus, endoplasmic reticulum. Thus, the eukaryotic cell is partitioned by internal membranes.
