12 multiple choice 1 point
which one of the following structures is characteristic of both eukaryotic and prokaryotic cells?
golgi apparatus
cell membrane
nucleus
endoplasmic reticulum
mitochondria

Explanation:

For question 11: The cell theory has three core tenets: all life is made of cells/cell products, cells arise from preexisting cells, and the cell is the basic unit of life. Prokaryotic cells lack a nucleus and membrane-bound organelles, so the statement claiming all cells have these is incorrect.
For question 12: Prokaryotic cells lack membrane-bound organelles (Golgi, nucleus, ER, mitochondria). Both prokaryotic and eukaryotic cells have a cell membrane to enclose their contents.

Answer:

1. B. All cells have a nucleus and organelles.
2. B. cell membrane
