Which statement best defines photosynthesis based on the lesson visuals?

• The breakdown of glucose to release energy

• The process in which plants use sunlight to convert water and carbon dioxide into glucose and oxygen

• The absorption of oxygen to form carbon dioxide

• The movement of water from roots to leaves

Which form of energy is converted into chemical energy during photosynthesis?

• Mechanical energy

• Heat energy from soil

• Light energy (sunlight)

• Electrical energy

According to the diagram, which substances are reactants in photosynthesis?

• Glucose and oxygen

• Water and carbon dioxide

• Oxygen and sunlight

• Glucose and sunlight

Which pair lists products of photosynthesis?

• Water and carbon dioxide

• Glucose and oxygen

• Glucose and carbon dioxide

• Water and oxygen

Which balanced chemical equation represents photosynthesis?

• C6H12O6 + 6O2 → 6CO2 + 6H2O

• 6CO2 + 6H2O → C6H12O6 + 6O2

• 6O2 + C6H12O6 → 6CO2 + 6H2O

• 6H2O + 6O2 → C6H12O6 + 6CO2

In the word equation for photosynthesis, what are the reactants?

• Sugar and oxygen

• Carbon dioxide and water

• Water and glucose

• Oxygen and glucose

Which statement correctly describes the energy conversion in photosynthesis?

• Chemical energy is converted into light energy

• Light energy is converted into chemical energy stored in glucose

• Heat energy is converted into mechanical energy

• Electrical energy is converted into heat energy

A student claims that oxygen is a reactant of photosynthesis. Using the provided equation, evaluate the claim.

• Correct, because oxygen appears on the left side of the equation

• Incorrect, because oxygen is produced and appears on the right side of the equation

• Correct, because plants absorb oxygen from the air

• Incorrect, because oxygen is neither produced nor consumed

If carbon dioxide supply to a plant decreases, which immediate outcome is most likely according to the photosynthesis equation?

• More glucose will be produced

• Less oxygen will be produced

• Water production will increase

• Light energy will stop reaching the plant

Which organelle is the primary site of photosynthesis in plant cells?

• Mitochondrion

• Chloroplast

• Nucleus

• Golgi apparatus

• Ribosome
