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

Where does the Calvin Cycle take place?

Back

The Calvin Cycle takes place in the stroma of chloroplasts.

Front

What is the primary gas consumed during photosynthesis?

Back

The primary gas consumed during photosynthesis is carbon dioxide.

Front

What gas is released as a byproduct of photosynthesis?

Back

Oxygen is released as a byproduct of photosynthesis.

Front

What are the light-dependent reactions?

Back

Light-dependent reactions are the first stage of photosynthesis, occurring in the thylakoid membranes, where light energy is converted into chemical energy (ATP and NADPH) and oxygen is released.

Front

What factors affect the rate of photosynthesis?

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily in the blue and red wavelengths, to drive the process of photosynthesis.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the significance of photosynthesis to life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen and organic compounds that serve as food for most living organisms.

Front

What is the difference between light-dependent and light-independent reactions?

Back

Light-dependent reactions require light to produce ATP and NADPH, while light-independent reactions (Calvin Cycle) do not require light and use ATP and NADPH to synthesize glucose.
