A student noticed that the freshwater plant, Elodea, produced bubbles when placed in direct light. What could the student most likely conclude?

• Bubbles of carbon dioxide were produced as a result of photosynthesis.

• Bubbles of oxygen were produced as a result of photosynthesis.

• Bubbles of carbon dioxide were produced as a result of cellular respiration

• Bubbles of oxygen were produced as a a result of cellular respiration

These diagrams show a variety of cells from the same organism. How can cells from the same organism have such different shapes and functions?

• As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity.

• Mutations in the cells' nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.

• During differentiation, different parts of the DNA in each type of cell are activated, resulting in the different structure and function of the cells.

• During differentiation, different types of cells produce proteins which destroy the nonactive DNA, leading to cell specialization.

A contractile vacuole helps protists eliminate excess liquid. This is a "pumping" process which reduces pressure inside the cell and prevents the cell from bursting. What is most likely the source of energy for this process?

• DNA

• lipids

• ATP

• ribosomes

Which statement best describes the relationship between the products of photosynthesis and the reactants in cellular respiration?

• The products of photosynthesis serve as the reactants in cellular respiration to provide chemical energy.

• The products of photosynthesis combine with the reactants in cellular respiration to remove ATP from cells.

• The products of photosynthesis inhibit the reactants in cellular respiration in the presence of light.

• The products of photosynthesis change the structure of the reactants in cellular respiration in the presence of light.
