04-Cell Biology

All cells on the planet (at least all the ones we know about) are either prokaryotic or eukaryotic.

Prokaryotic cells are unorganized.

Fungi and plants have cell walls.

Cell walls are the primary regulator of what atoms or molecules get into or out of the cell.

A water molecule that passes across the plasma membrane into the interior of a prokaryotic cell will be in the cell's cytoplasm.

A water molecule that passes across the plasma membrane into the interior of a eukaryotic cell will be in the cell's endoplasmic reticulum.

Prokaryotic cells have a different genetic code than eukaryotic cells.

Both prokaryotic and eukaryotic cells can have flagella with similar structures.

Only eukaryotic cells are capable of moving in a particular direction.

Pilli are rods that extend from some bateria into their environment.

A molecule of RNA is transported out of the nucleus through a nuclear pore. Where would it be?


A. In the cytoplasm B. In the nuclear envelope C. In the nucleolus D. In the endoplasmic reticulum

Where does protein synthesis occur in prokaryotic cells?

A. In the cytoplasm B. In the endoplasmic reticulum C. In the nucleoid

Where does protein synthesis occur in eukaryotic cells?

A. In the cytoplasm B. In the nucleoid C. In the endoplasmic reticulum

Mitochondria have ribosomes in their interior.

Chloroplasts have ribosomes in their interior.
