Photosynthesis Review

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 glucose and oxygen.

Front

What role do chlorophyll and chloroplasts play in photosynthesis?

Back

Chlorophyll is the green pigment found in chloroplasts that absorbs sunlight, while chloroplasts are the organelles in plant cells where photosynthesis takes place.

Front

What is the significance of stomata in photosynthesis?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange; they enable carbon dioxide to enter the leaf and oxygen to exit.

Front

How does light intensity affect the rate of photosynthesis?

Back

In general, as light intensity increases, the rate of photosynthesis increases, up to a certain point, after which it may plateau.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Front

What happens to glucose produced during photosynthesis?

Back

Glucose can be used immediately for energy, stored as starch for later use, or used to build other organic molecules.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis; it provides electrons and protons needed for the formation of glucose and oxygen.

Front

How does carbon dioxide enter the plant?

Back

Carbon dioxide enters the plant through the stomata during the process of gas exchange.

Front

What factors can limit the rate of photosynthesis?

Back

Factors that can limit the rate of photosynthesis include light intensity, carbon dioxide concentration, temperature, and water availability.
