Front

What is chlorophyll and what is its function in plant cells?

Back

Chlorophyll is a pigment that absorbs sunlight for photosynthesis.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What role do chloroplasts play in plant cells?

Back

Chloroplasts are the organelles where photosynthesis occurs, converting light energy into chemical energy.
