Front

What is photosynthesis?

Back

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What is chlorophyll?

Back

A green pigment found in plants that is essential for photosynthesis.

Front

What are thylakoids?

Back

Membrane-bound compartments inside chloroplasts where the light-dependent reactions of photosynthesis occur.

Front

What is the role of the Electron Transport Chain in photosynthesis?

Back

It transfers electrons and pumps H+ ions to create a proton gradient.

Front

What is the significance of the light-dependent reactions?

Back

They convert light energy into chemical energy in the form of ATP and NADPH.
