Photosynthesis and Cellular Respiration

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.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (a sugar) and oxygen.

Front

What is the chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

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.

Front

What is the chemical equation for cellular respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP).

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 cells.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment in chloroplasts that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis and release oxygen, playing a crucial role in the carbon cycle.

Front

What is the role of animals in the carbon cycle?

Back

Animals release carbon dioxide into the atmosphere through respiration and decomposition, and they contribute to carbon sequestration through biomass formation and plant consumption.
