Unit 2 Task Cards: Photosynthesis

#1 In your own words, what is photosynthesis?

• A process plants undergo to break down chemical energy (glucose) into ATP
• A process animals undergo to transform solar energy into chemical energy (glucose)
• A process all cells undergo to break down chemical energy (glucose) into ATP
• A process plants undergo to transform solar energy into chemical energy (glucose)

#2 What is the name of the organelle where photosynthesis takes place?

• cell membrane
• mitochondria
• chloroplast
• cytoplasm

#3 This is one of the end products of photosynthesis. What is it?

• glucose
• oxygen
• amino acid
• carbon dioxide

#4 What are some factors that affect the rate of photosynthesis?

• oxygen levels, light intensity, temperature, and light color
• oxygen levels, light intensity, temperature, and pH
• carbon dioxide levels, light intensity, temperature, and oxygen levels
• carbon dioxide levels, light intensity, temperature, and light color

#5 How is oxygen in the air made during photosynthesis?

• Oxygen (O₂) is released from the chloroplast after sunlight splits water (H₂O)
• Oxygen (O₂) is released from the chloroplast after sunlight splits carbon dioxide (CO₂)

#6 What molecule do plants pull from the air that is used to make sugar?

• water (H₂O)
• carbon dioxide (CO₂)
• oxygen (O₂)
• adenosine triphosphate (ATP)

#7 What is the chemical formula for glucose?

• CO₂
• O₂
• H₂O
• C₆H₁₂O₆

#8 What are the reactants of photosynthesis?

• solar energy, water (H₂O), and glucose (C₆H₁₂O₆)
• oxygen (O₂) and glucose (C₆H₁₂O₆)
• solar energy, water (H₂O), and carbon dioxide (CO₂)
• oxygen (O₂) and water (H₂O)

#9 What are the products of photosynthesis?

• solar energy, water (H₂O), and carbon dioxide (CO₂)
• solar energy, water (H₂O), and glucose (C₆H₁₂O₆)
• oxygen (O₂) and glucose (C₆H₁₂O₆)
• oxygen (O₂) and water (H₂O)

#12 What is the equation for photosynthesis?

• light + 6O₂ + C₆H₁₂O₆ -----> 6H₂O + 6CO₂
• light + 6H₂O + 6CO₂ -----> 6O₂ + C₆H₁₂O₆
• 6O₂ + C₆H₁₂O₆ -----> 6H₂O + 6CO₂ + ATP
• light + 6CO₂ -----> 6O₂ + C₆H₁₂O₆
