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 product of photosynthesis?

Back

The main product of photosynthesis is glucose.

Front

What gas do plants take in during photosynthesis?

Back

Plants take in carbon dioxide during photosynthesis.

Front

What gas do animals release during cellular respiration?

Back

Animals release carbon dioxide during cellular respiration.

Front

How does light intensity affect photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis, up to a certain point.

Front

What role does chlorophyll play in photosynthesis?

Back

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

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.

Front

What factors can affect the rate of photosynthesis?

Back

Factors include light intensity, carbon dioxide concentration, temperature, and water availability.
