Explanation:

Part II: Fill in the Blank

1. Photosynthesis occurs in plant cell organelles that capture light.
2. Sunlight provides the energy for photosynthesis.
3. Photosynthesis produces sugar as its main food product.
4. Cellular respiration occurs in the organelle that breaks down fuel.
5. Respiration releases energy stored in a high-energy molecule.
6. Photosynthesis releases a gas needed for animal respiration.
7. Photosynthesis uses two key raw materials from air/water.
8. Both plants and animals break down sugar for energy via respiration.

1. Only plants (and some bacteria) perform photosynthesis among the options.
2. Aerobic cellular respiration requires oxygen to break down fuel.
3. Photosynthesis converts light energy into stored chemical energy in glucose.
4. Cellular respiration (aerobic) generates far more ATP than other listed processes.
5. Chloroplasts are unique to plant cells for photosynthesis; animals lack them.

Answer:

1. chloroplasts
2. light energy
3. glucose
4. mitochondria
5. ATP
6. oxygen
7. carbon dioxide; water
8. glucose
