Photosynthesis & Cell Respiration AYER 2025

If carbon dioxide is removed from a plant’s environment, what would you expect to happen?

• More sugars will be produced.

• No sugars will be produced.

• The same number of sugars will be produced but without carbon dioxide.

• Carbon dioxide does not affect the production of high-energy sugars in plants.

How do photosynthesis and cellular respiration differ?

• photosynthesis uses food and cellular respiration produces food
• photosynthesis creates and stores glucose for energy and cellular respiration breaks glucose to release energy

• photosynthesis uses oxygen and cellular respiration uses carbon dioxide
• photosynthesis makes ATP and cellular respiration uses sunlight

Why are plants green?

• because of a green pigment called chlorophyll

• because of a green pigment called chlorplast

• the glucose they create is green

• the water they drink causes them to turn green

Why is photosynthesis important for humans and animals?

• the oxygen we breath is created during photosynthesis

• the carbon dioxide we breath is created during photosynthesis

• the water we drink is created during photosynthesis

• the food we eat is created during photosynthesis
