Front

What is the ultimate ORIGINAL source of energy for living things?

Back

Sun

Front

What is photosynthesis?

Back

The process in which plants make their food.

Front

How does carbon dioxide get into the leaves of a plant?

Back

It enters through the stomata.

Front

Where do the dark reactions (Calvin cycle) take place?

Back

Stroma.

Front

What are the two products of the light reactions that are needed for the Calvin cycle?

Back

NADPH and ATP.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs sunlight, which is essential for the process of photosynthesis.

Front

What are the main reactants of photosynthesis?

Back

Carbon dioxide and water.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is the significance of oxygen produced during photosynthesis?

Back

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

Front

What is the difference between light reactions and dark reactions in photosynthesis?

Back

Light reactions convert solar energy into chemical energy (ATP and NADPH), while dark reactions (Calvin cycle) use that energy to synthesize glucose.
