Photosynthesis Review

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 are the main pigments involved in photosynthesis?

Back

The main pigments involved in photosynthesis are chlorophyll a, chlorophyll b, and carotenoids.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs sunlight, primarily in the blue and red wavelengths, and converts it into chemical energy.

Front

What is the overall equation for photosynthesis?

Back

6CO2 + light + 6H2O --> 6O2 + glucose.

Front

What are thylakoids?

Back

Thylakoids are membrane-bound structures within chloroplasts where the light-dependent reactions of photosynthesis occur.

Front

What is the function of light-dependent reactions?

Back

Light-dependent reactions convert solar energy into chemical energy in the form of ATP and NADPH, releasing oxygen as a byproduct.

Front

What is the function of the Calvin cycle?

Back

The Calvin cycle uses ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose.

Front

What is a producer in an ecosystem?

Back

A producer is an organism that can make its own food through photosynthesis or chemosynthesis.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is produced as a byproduct of photosynthesis and is essential for the respiration of most living organisms.

Front

How do environmental factors affect photosynthesis?

Back

Factors such as light intensity, carbon dioxide concentration, and temperature can significantly influence the rate of photosynthesis.
