• Explain the common similarity in all prokaryotic and eukaryotic cells.

Explain the similarity in at least two sentences. ANS The fundamental similarity is that each cell type has a plasma membrane that separates life from non-life. The plasma membrane acts as a barrier to most molecules but does have proteins that permit select molecules to cross via proteins (transporters). The plasma membrane permits the cell to have a different composition of molecules inside the cell than out and defines a space for life to occur.
