The organelle responsible for making sugars in eukaryotes is the chloroplast.

Here's why:

* Photosynthesis: Chloroplasts are the sites of photosynthesis. Photosynthesis is the process by which plants and some algae use sunlight, water, and carbon dioxide to create glucose (a type of sugar) and oxygen.

* Plant Cells: Chloroplasts are primarily found in plant cells, but they are also present in some algae.

While other organelles play a role in energy production and metabolism, the chloroplast is the unique organelle dedicated to sugar production through photosynthesis.
