Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + H₂O (+light) --> O₂ + Sugar

• CO₂ + sugar + H₂O --> O₂ (+light)

• O₂ + H₂O (+light) --> CO₂ + Sugar

• CO₂ + O₂ + H₂O --> Sugar (+light)

Which organelle performs CELLULAR RESPIRATION?

• Chloroplast

• Mitochondria

Which organisms perform Photosynthesis?

• Only Autotrophs

• Only Heterotrophs

• Autotrophs and Heterotrophs

What are the PRODUCTS for cellular respiration?

• oxygen and ATP (energy)

• water and glucose and ATP (energy)

• carbon dioxide and water and ATP (energy)

• glucose and oxygen

What is the purpose of photosynthesis?

• Store the sun's energy in glucose

• Store the sun's energy in ATP

• Release energy from glucose

• release energy from ATP

How can photosynthesis be related to cellular respiration?

• What's produced (made) by one is needed (the reactants) for the other

• They both produce the same products (outputs)

• They both have the same reactants (inputs)

• These 2 processes have nothing in common

Use the diagram to answer the question. Between which parts of the molecule must the bonds be broken to form an ADP molecule?

• A and B

• A and C

• B and C

• C and D

How do plants get the food they need?

• From the soil

• They create it through photosynthesis

• Plants don't need food

• By eating insects

Photosynthesis benefits animals (heterotrophs) because

• Animals can learn to perform photosynthesis

• Animals use the food and oxygen created by photosynthesis

• Animals use plants only for oxygen

• Animals do not benefit from photosynthesis

What is the purpose of cellular respiration?

• To break down glucose into ATP

• To store energy from sunlight in glucose

• To breathe

• To increase the size of cells
