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 are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

What is the role of chloroplasts in photosynthesis?

Back

Chloroplasts are the organelles in plant cells where photosynthesis takes place, containing chlorophyll that captures light energy.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions that occur in the stroma of chloroplasts, where carbon dioxide is converted into glucose.

Front

What factors affect the rate of photosynthesis?

Back

The rate of photosynthesis is affected by light intensity, carbon dioxide concentration, temperature, and water availability.

Front

What is the significance of chlorophyll in photosynthesis?

Back

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

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) use ATP and NADPH to synthesize glucose.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis that provides electrons and protons, and it is split to release oxygen as a byproduct.

Front

How does temperature affect photosynthesis?

Back

Temperature affects the enzymes involved in photosynthesis; too high or too low temperatures can slow down or halt the process.
