What is something all eukaryotic cells have in common? A.)All Cells are round
B.)All cells have a nucleus
C.)All cells have a cell wall
D.)All cells have cytoplasm

We can immediately rule out option A, because not all cells are round. We can also rule out option C because not all cells have a cell wall. Animal cells, for instance, do not.

Can you choose more than one option? Because if so, the answers would be both B and D. All cells, no matter what type, have cytoplasm. Only eukaryotic cells have a true nucleus.
