Photosynthesis, Cellular Respiration and Energy

What is photosynthesis?

• The process in which humans eat their food
• When a photographer takes a photo.
• To get your pictures from the photo lab.
• The process in which plants make their food.

The three things plants need are sunlight, water, and CO2 for photosynthesis.

• True
• False

What are the two products of photosynthesis?

• Oxygen and Carbon Dioxide
• Oxygen and Sugar
  

• Sunlight and Sugar

What are the reactants in Photosynthesis?

• Sun, CO2, glucose

• glucose and oxygen

• sun, carbon dioxide, water

• water, glucose

What are the products of photosynthesis?

• Water + Glucose

• Glucose + Carbon dioxide

• Glucose + Oxygen

• Carbon dioxide + Oxygen

For photosynthesis, a plant needs water, sun, and...

• oxygen

• carbon dioxide

• glucose

• mitochondria

Cell organelle where most reactions of cellular respiration occurs is the:

• ribosome

• mitochondria

• lysosome

• Gogi apparatus

Which of these is NOT AN IMPACT photosynthesis has on an ecosystem:

• Oxygen for animals and humans to breathe
• Food for us to eat
• Taking CO₂ out of the air
• Taking oxygen out of the air

Cellular respiration is...

• the process by which cells break down glucose into energy.

• the process by which cells break light down into energy.

• the process by which cells communicate with other cells.

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 uses carbon dioxide, while cellular respiration produces carbon dioxide.
