Photosynthesis

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 are the main products of photosynthesis?

Back

The main products of photosynthesis are oxygen and glucose.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a key reactant in photosynthesis; it is used by plants to produce glucose.

Front

How does light intensity affect the rate of photosynthesis?

Back

As light intensity increases, the rate of photosynthesis generally increases until it reaches a saturation point.

Front

What is the chemical equation for photosynthesis?

Back

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂.

Front

What is the significance of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, which is essential for photosynthesis.

Front

What happens to the rate of photosynthesis if carbon dioxide levels are low?

Back

If carbon dioxide levels are low, the rate of photosynthesis will decrease because carbon dioxide is a necessary reactant.

Front

What is the effect of temperature on photosynthesis?

Back

Temperature affects the rate of photosynthesis; too low or too high temperatures can slow down or inhibit the process.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy, while cellular respiration produces carbon dioxide and water, which are used in photosynthesis.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis; it is split to provide electrons and protons for the formation of glucose.
