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 is the role of chloroplasts in plants?

Back

Chloroplasts are the organelles in plant cells where photosynthesis occurs, converting light energy into chemical energy.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to store and transfer energy for various cellular processes.

Front

What gas do plants take in during photosynthesis?

Back

Plants take in carbon dioxide (CO2) from the atmosphere during photosynthesis.

Front

What do plants release as a byproduct of photosynthesis?

Back

Plants release oxygen (O2) as a byproduct of photosynthesis.

Front

Why do plants appear green?

Back

Plants appear green because chlorophyll, the pigment in chloroplasts, reflects green light and absorbs other wavelengths of light for photosynthesis.

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 cellular respiration?

Back

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

Front

What is the main purpose of photosynthesis?

Back

The main purpose of photosynthesis is to convert light energy into chemical energy stored in glucose, which can be used by the plant for growth and energy.
