5 0

Answer:

All eukaryotic cells have a membrane that covers them, internal fluid and a central nucleus, so the correct answer is option d (All of the above).

Explanation:

Eukaryotic cells are those that possess a plasma membrane that surrounds them, acting as a semi-permeable membrane to the passage of substances, in addition to possessing the capacity to receive external signals.

The cytoplasmic membrane of eukaryotic cells is related to an endomembrane system, associated to cytoplasmic organelles and to the central nucleus, which stores genetic information, in the form of DNA.

The eukaryotic cell cytoplasm is fluid and serves as a support for the organelles, as well as all the chemicals suspended in it.

<u>The existence of true nucleus and organelles is what defines a eukaryotic cell and differentiates them from prokaryotic cells</u>.
