Question

which sentence describes prokaryotic cells and eukaryotic cells?
o a. they both contain a nucleus that holds dna.
o b. they both have plasma membranes.
o c. they have the same internal structures.
o d. they both have chloroplasts.

Explanation:

Prokaryotic cells lack a nucleus (DNA is in the cytoplasm), while eukaryotic cells have a nucleus. Both types of cells are enclosed by a plasma membrane (cell membrane) that regulates what enters and exits the cell. They do not have the same internal structures (eukaryotes have membrane-bound organelles like mitochondria, which prokaryotes lack), and chloroplasts are only present in some eukaryotes (e.g., plants, algae), not prokaryotes.

Answer:

B. They both have plasma membranes.
