• Sunlight is absorbed and converted into energy.

• Energy (ATP) is released from sugars without oxygen present.

• Energy (ATP) is released from sugars when oxygen is available.

What is the relationship between the two cell structures?

• Chloroplasts use glucose to make energy, and mitochondria use energy to make glucose.

• Chloroplasts use energy to make glucose, and mitochondria use glucose to make energy.

• Chloroplasts and mitochondria transform solar energy into chemical energy for the cell.
