Cell Structure, Function, and Transport

A plant and an animal are both living things. According to the Cell Theory, what can you conclude about these two very different organisms?

• Plants have cells but animals do not.

• They are both made of one or more cells.

• They both come from the same kind of cell.

• They both come from a non-living organism.

The combined observations of Mattias Schleiden, Theodor Schwann and Rudolph Virchow resulted in the formation of the cell theory. Which of the following is not part of the cell theory?

• All cells contain a nucleus.

• All cells come from other living cells.

• All living organisms are made of one or more cells.

• Cells are the basic unit of structure and function of all living things.

There are some similarities between prokaryotic and eukaryotic cells. Which of the following structures is found in both prokaryotic and eukaryotic cells?

• lysosome

• mitochondrion

• active transport

• passive transport

• facilitated diffusion

• co-transport

Which type(s) of cells have genetic material that is contained in a nucleus?

• bacteria

• plants only

• animals only

• both plant and animal cells

A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. Which of the following has occurred?

• The swollen gums have absorbed the saltwater solution.

• The saltwater solution lowers the temperature of the water in the gums.

• The salt in the solution has moved against the concentration gradient.

• The water in the gums has moved out due to the high concentration of salt in the solution.
