Photosynthesis and Respiration

What is the process by which green plants convert light energy, carbon dioxide, and water into glucose and oxygen called?

• Fermentation

• Photosynthesis

Why is photosynthesis important for life on Earth?

• It produces carbon dioxide and water.

• It is the primary source of oxygen production and provides food for most living organisms.

What is the correct equation for photosynthesis?

• 6CO2 (carbon dioxide) + 6H2O (water) + light energy = C6H12O6 (glucose) + 6O2 (oxygen)

• 6O2 (oxygen) + C6H12O6 (glucose) + light energy = 6CO2 (carbon dioxide) + 6H2O (water)

What are chloroplasts?

• A type of sugar produced during photosynthesis.

• Structures in plant cells where photosynthesis occurs.

What is the primary product of photosynthesis that serves as a food source?

• Glucose

• Carbon dioxide

What are the two stages of photosynthesis?

• Stage 1: Capturing water, Stage 2: Using water to create sugar

• Stage 1: Capturing energy (sunlight), Stage 2: Uses energy to create sugar and oxygen

How do plants obtain CO2 for photosynthesis?

• From the soil

• Through the Stomata

What are the products of photosynthesis?

• Oxygen and Glucose

• Carbon Dioxide and Water

Where does the first stage of respiration take place and how much energy is produced?

• In the cytoplasm, producing a small amount of energy

• In the chloroplasts, producing no energy
