Chloroplasts contribute to the function of the cell because they CONVERT energy from the sun into glucose.
Chloroplasts are organelles found in plants and some algae that act to harvest the energy from the sun in order to produce ATP and subsequently simple carbohydrates (glucose) by a process known as photosynthesis.
Photosynthesis has two types of reactions: light-dependent reactions and light-independent reactions.
The light-dependent reactions that produce ATP occur in the thylakoid membrane of the chloroplasts.
The light-independent reactions that produce simple carbohydrates occur in the stroma of the chloroplast.
In conclusion, chloroplasts contribute to the function of the cell because they CONVERT energy from the sun into glucose.
