Photosynthesis and Cell 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.

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 main difference between photosynthesis and cellular respiration?

Back

Photosynthesis uses carbon dioxide and produces oxygen, while cellular respiration uses oxygen and produces carbon dioxide.

Front

Which organelle is responsible for photosynthesis in plant cells?

Back

Chloroplasts are the organelles in plant cells that perform photosynthesis.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What are the main reactants of photosynthesis?

Back

The main reactants of photosynthesis are carbon dioxide and water.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

How do plants absorb water?

Back

Plants absorb water through their roots, which then travels up the xylem to the leaves.

Front

What is the significance of stomata in plants?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, enabling the intake of carbon dioxide and the release of oxygen.

Front

What factors affect the rate of photosynthesis?

Back

The rate of photosynthesis can be affected by the amount of water, carbon dioxide concentration, temperature, and light intensity.
