Photosynthesis & Respiration (Science 8)

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 and oxygen.

Front

What organelle is responsible for photosynthesis in plant cells?

Back

Chloroplasts are the organelles responsible for photosynthesis in plant cells.

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 are the main reactants of aerobic cellular respiration?

Back

The main reactants of aerobic cellular respiration are glucose and oxygen.

Front

What is the role of mitochondria in cells?

Back

Mitochondria are known as the powerhouse of the cell; they break down glucose to release energy for the cell.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the equation for aerobic cellular respiration?

Back

The equation for aerobic cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP).

Front

What is the importance of oxygen in respiration?

Back

Oxygen is essential for aerobic respiration as it acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more energy (ATP) compared to anaerobic respiration, which occurs without oxygen and produces less energy.
