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 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 Autotrophs?

Back

Autotrophs are organisms that produce their own food through photosynthesis or chemosynthesis, such as plants and some bacteria.

Front

What are Heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy, such as animals and fungi.

Front

What is the main difference between Photosynthesis and Cellular Respiration?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration converts glucose and oxygen into carbon dioxide and water, releasing energy.

Front

What is the equation for Photosynthesis?

Back

The equation for photosynthesis is: CO₂ + light + H₂O → O₂ + glucose.

Front

What is the role of Chloroplasts in plants?

Back

Chloroplasts are the organelles in plant cells where photosynthesis takes place, containing chlorophyll that captures light energy.

Front

What is the role of Mitochondria in cells?

Back

Mitochondria are the organelles in cells where cellular respiration occurs, producing ATP, the energy currency of the cell.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy-carrying molecule found in the cells of all living things, used to store and transfer energy.

Front

What is the significance of Oxygen in Photosynthesis?

Back

Oxygen is a byproduct of photosynthesis, released into the atmosphere, and is essential for the survival of aerobic organisms.
