Photosynthesis and respiration review

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

Where does cellular respiration occur in cells?

Back

Cellular respiration occurs in the mitochondria of cells.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for photosynthesis to convert carbon dioxide and water into glucose and oxygen.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen is a reactant in cellular respiration that helps to break down glucose to release energy.

Front

How do photosynthesis and cellular respiration relate to each other?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.
