Question

select the part whose main job is to use energy from sunlight to make sugar. vacuole chloroplast smooth endoplasmic reticulum chromosomes

Explanation:

To solve this, we analyze each option:

• Vacuole: Stores substances, not involved in making sugar from sunlight.
• Chloroplast: In plant cells, it performs photosynthesis, using sunlight to convert carbon dioxide and water into sugar (glucose) and oxygen.
• Smooth Endoplasmic Reticulum: Involved in lipid synthesis and detoxification, not sugar production from sunlight.
• Chromosomes: Contain genetic material, not related to photosynthesis.

So the part that uses sunlight energy to make sugar is the chloroplast.

Answer:

chloroplast
