Cell Unit Review

Which statement concerning the structures within this cell is accurate?

• Structure 1 is a chloroplast that carries out photosynthesis.

• Structure 2 is a vacuole that contains DNA.

• Structure 3 is a mitochondrion, where respiration takes place.

• Structure 4 is the cell membrane, which provides rigid support for the cell.

Base your answer to this question on the information and diagram below and on your knowledge of biology. The diagram represents red blood cells placed in three test tubes, each containing a different salt solution. Which statement best describes test tube C?

• The concentration of dissolved salt in the solution is greater than the concentration in the cells.

• The concentration of dissolved salt in the solution is less than the concentration in the cells.

• The concentration of water in the solution is greater than the concentration in the cells.

• The concentration of water in the solution is equal to the concentration in the cells.

The water used on slide A contained 1% salt and 99% water. The salt solution used on slide B contained 6% salt and 94% water. Elodea cells normally contain 1% salt.

Five minutes after the slides were prepared, a student using a compound light microscope to observe the cells in leaves A and B would most likely see that

• water had moved out of the cells of the leaf on slide A

• salt had moved out of the cells of the leaf on slide B

• salt had moved into the cells of the leaf on slide A

• water had moved out of the cells of the leaf on slide B

The diagram shows an experimental setup using an artificial plant cell. Molecules A and B are commonly found in plant cells. When tested, it was discovered that molecule A quickly passed through the artificial plant cell membrane. Molecule B did not pass through. The locations of molecules A and B at the beginning of the experiment are shown. Which statement best describes what was observed when the setup was examined 20 minutes later?

• Only molecule A was found both inside and outside the artificial cell.

• Both molecules A and B were found inside and outside the artificial cell.

• Molecule A remained inside the artificial cell and molecule B remained outside

• Only molecule B was found both inside and outside the artificial cell.
