The organelle in plant cells that turns energy from sunlight into food is the chloroplast.

Here's a breakdown:

* Chloroplasts are the sites of photosynthesis. They contain a green pigment called chlorophyll, which absorbs light energy.

* This light energy is used to convert carbon dioxide and water into glucose (a type of sugar) and oxygen.

* The glucose is the plant's food source, providing energy for growth and other functions.

* Oxygen is released as a byproduct of photosynthesis.

So, in short, chloroplasts are like tiny solar panels within the plant cell, converting sunlight into the energy the plant needs to survive and thrive.
