Hoffman Period 1 Photosynthesis/Cellular Respiration Post-Quiz

The reactants of photosynthesis are

• sugar and water

• sugar and oxygen

• carbon dioxide and water

• carbon dioxide and oxygen

Which statement about photosynthesis is correct?

• Plants get the energy they need for photosynthesis from water.

• Plants get the energy they need for photosynthesis from soil.

• Plants get the energy they need for photosynthesis from sunlight.

• Plants do not require energy to perform photosynthesis.

What are the products of photosynthesis?

• carbon dioxide and water

• carbon dioxide and oxygen

• glucose and oxygen

• glucose and water

Which of the following is the correct equation for PHOTOSYNTHESIS?

• 6CO₂ + 6H₂O → 6O₂ + C₆H₁₂O₆

• 6CO₂ + C₆H₁₂O₆ + 6H₂O → O₂

• 6O₂ +6H₂O → 6CO₂ +C₆H₁₂O₆

• C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂

Which gas is removed from the atmosphere during photosynthesis?

• hydrogen

• oxygen

• nitrogen

• carbon dioxide

What are the reactants (what's needed) for photosynthesis?

• glucose and oxygen
• light, water, and carbon dioxide

In which organelle (part of the cell) does photosynthesis take place?

• mitochondria
• chloroplast
• nucleus
• cell membrane

In which way are photosynthesis and cellular respiration different?

• Cellular respiration stores ATP, while photosynthesis releases ATP.
• Cellular respiration produces oxygen, while photosynthesis uses oxygen.
• Photosynthesis releases energy, while cellular respiration stores energy.
• Photosynthesis used carbon dioxide, while cellular respiration produces carbon dioxide.

Cellular Respiration's goal is to

• make water
• make ATP
• make glucose
• make  oxygen

1. What is chlorophyll and how does it help plants?

• A.Chlorophyll is a pigment that absorbs light energy and makes glucose.

• B.Chlorophyll is a protein that changes shape in the presence of sunlight.

• C.Chlorophyll is a receptor that binds carbon dioxide when energized by light

• D.Chlorophyll is an enzyme that catalyzes the production of glucose when exposed to light.
