#22 Photosynthesis

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 the chemical equation for photosynthesis?

Back

6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂

Front

What are the main products of photosynthesis?

Back

Oxygen and glucose.

Front

Which organelle is responsible for photosynthesis?

Back

Chloroplast.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What gas is taken in by plants during photosynthesis?

Back

Carbon dioxide (CO₂).

Front

What is the significance of oxygen produced during photosynthesis?

Back

Oxygen is released into the atmosphere as a byproduct of photosynthesis, which is essential for the respiration of most living organisms.

Front

What is the role of water in photosynthesis?

Back

Water (H₂O) is a reactant in the photosynthesis process, providing electrons and protons needed for the formation of glucose.

Front

How does light intensity affect photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis, up to a certain point, after which other factors may limit the process.

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.
