When the volume of a cell increases, its surface area ...

• increases at the same rate

• remains the same

• increases at a faster rate

• increases at a slower rate

Surface area is an important factor in limiting cell growth, because ...

• the cell can burst if the membrane becomes too large

• materials cannot enter the cell if the surface is too large

• the cell may become too large to take in enough food and to remove enough wastes

• waste products cannot leave the cell if the cell is too small

One difference between prokaryotes and eukaryotes is that ...

• nucleic acids are found only in prokaryotes

• mitochondria are found in larger quantities in eukaryotes

• the golgi apparatus is found only in prokaryotes

• prokaryotes have no nuclear membrane

Which of the following is an example of a prokaryotic cell?

• an amoeba

• a virus

• a bacterium

• a liver cell

Only eukaryotic cells have ...

• DNA

• membrane-bound organelles

• ribosomes

• cytoplasm

The plasma membrane ...

• encloses the contents of a cell.

• allows material to enter and leave the cell.

• is selectively permeable.

• All of the above

A particularly active cell might contain large numbers of

• chromosomes

• vacuoles

• mitochondria

• walls

The Golgi apparatus is an organelle that ...

• receives proteins and lipids from the endoplasmic reticulum.

• labels the molecules made in the endoplasmic reticulum with tags that specify their destination.

• releases molecules in vesicles.

• All of the above
