Back

Pigments.

Front

Why do plants appear green?

Back

Chlorophyll doesn't absorb green light.

Front

What is photosynthesis?

Back

The process by which plants convert light energy into chemical energy.

Front

Front

What is the role of thylakoids in chloroplasts?

Back

They are the sites where the light-dependent reactions of photosynthesis occur.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.
