Cellular Energy: Photosynthesis vs Cellular Respiration

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water, and releasing oxygen as a byproduct.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water. It occurs in both plant and animal cells.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

Where does cellular respiration occur in cells?

Back

Cellular respiration occurs in the mitochondria of both plant and animal cells.

Front

What are the main reactants of photosynthesis?

Back

The main reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

The main reactants of cellular respiration are glucose (C6H12O6) and oxygen (O2).

Front

What are the main products of cellular respiration?

Back

The main products of cellular respiration are carbon dioxide (CO2), water (H2O), and ATP (energy).

Front

How are photosynthesis and cellular respiration related?

Back

The products of photosynthesis (glucose and oxygen) are the reactants for cellular respiration, and the products of cellular respiration (carbon dioxide and water) are the reactants for photosynthesis.

Front

What is the role of sunlight in photosynthesis?

Back

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