Front

What is the role of mitochondria in a cell?

Back

Mitochondria convert energy stored in food into a usable form (ATP) through cellular respiration.

What organelle is responsible for photosynthesis in plant cells?

Back

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy (glucose).

Front

What is the function of chloroplasts?

Back

Chloroplasts capture sunlight and use it to produce glucose from carbon dioxide and water.
