Energy Transformations in Organisms- 7.5A, 7.7A

What happens to the solar energy absorbed by plants during photosynthesis?

• It is recycled by plants and returned o the atmosphere.

• It is converted into oxygen and glucose.

• It is stored as heat within the plant for cellular function.

• It is transformed into chemical energy,
