Plants and 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 two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What gas is taken in by plants during photosynthesis?

Back

Carbon dioxide (CO2) is taken in by plants during photosynthesis.

Front

What is the primary product of photosynthesis?

Back

The primary product of photosynthesis is glucose.

Front

What role do chlorophyll and chloroplasts play in photosynthesis?

Back

Chlorophyll is the green pigment in chloroplasts that captures light energy, while chloroplasts are the organelles where photosynthesis occurs.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the function of roots in plants?

Back

Roots anchor the plant in the soil, absorb water and nutrients, and store energy.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis, released into the atmosphere during the light-dependent reactions.

Front

What are light-dependent reactions?

Back

Light-dependent reactions are the first stage of photosynthesis that convert light energy into chemical energy (ATP and NADPH) and produce oxygen.

Front

What are light-independent reactions (Calvin cycle)?

Back

Light-independent reactions, or the Calvin cycle, use ATP and NADPH from the light-dependent reactions to convert carbon dioxide into glucose.
