Cellular Respiration AND Photosynthesis

During cellular respiration, what do animal cells use to produce energy from food?

• sunlight
• meat
• water
• oxygen

During photosynthesis, what gas do plants release?

• oxygen
• carbon dioxide
• water
• nitrogen

Photosynthesis is important because....

• plants need air to breathe
• it makes the plants green
• it is the process by which plants make their own food
• without it the Earth would all be a desert

The process by which cells use oxygen to produce energy from food is called?

• photosynthesis
• transpiration
• cellular respiration
• germination

How do plants get their energy?

• photosynthesis
• cellular respiration
• sunlight
• light
  another plant

The process by which sugar is converted into energy (ATP) by living organisms is called

• photosynthesis
• cellular respiration

The products of cellular respiration are

• carbon dioxide, water, energy
• oxygen and sugar (glucose)

The products of photosynthesis are

• carbon dioxide, water, energy
• sugar (glucose), oxygen, water

Select the balanced equation that represents cellular respiration.

• C₆H₁₂O_{6 +} 6O₂ −−> 6CO₂ + 6H₂O + Energy

• 2C₆H₁₂O_{6 +} 4O₂ −−> 4CO_{2 +} 6H₂O + Energy

The reactants of photosynthesis

• CO2

• CO2, H2O

• CO2, H2O, Sunlight

• none of the above
