PSSA Review #10 (Photosynthesis)

Which of the statements below is correct?

• Photosynthesis takes place inside molecules called chloroplasts. Chloroplasts use chlorophyll to capture light energy needed for photosynthesis.

• Photosynthesis takes place inside cell structures called chloroplasts. Chloroplasts use chlorophyll to capture light energy needed for photosynthesis.

• Photosynthesis takes place inside molecules called chloroplasts. Chloroplasts use chlorophyll to capture chemical energy needed for photosynthesis.

• Cell diagrams are used to represent only the cells of unicellular organisms.

Plant cells can use the sugars from photosynthesis to get chemical energy. Cells get chemical energy from food through a series of chemical reactions called cellular respiration. These chemical reactions break down and rearrange food molecules to release chemical energy. Once chemical energy is released, cells can use it directly for growth and other cell processes that plants need to live.

What statement below summarizes the process?

• Cellular respiration releases chemical energy from sugars created during photosynthesis.

• Cellular respiration releases light energy from sugars created during photosynthesis.

• Cellular respiration releases chemical energy from water created during photosynthesis.

The light energy captured by chlorophyll is used to power the series of chemical reactions that make up photosynthesis. In these reactions, the atoms in water and carbon dioxide are rearranged to form sugars and oxygen. A plant's cells use the sugars as food and release the oxygen into the environment.

What statement below summarizes the process?

• Photosynthesis uses light energy to rearrange the atoms in water and carbon dioxide to make sugar and chlorophyll.

• Photosynthesis uses light energy to rearrange the atoms in water and carbon dioxide to make sugar and oxygen.

• Photosynthesis uses light energy to rearrange the atoms in water and oxygen to make sugar and carbon dioxide.
