The part of the plant cell that allows it to produce food from sunlight is the chloroplast.

Here's why:

* Chloroplasts are organelles found within plant cells. They contain a green pigment called chlorophyll.

* Chlorophyll absorbs sunlight, which provides the energy for photosynthesis.

* Photosynthesis is the process where plants convert sunlight, water, and carbon dioxide into glucose (sugar) for energy and oxygen as a byproduct.

So, chloroplasts are essential for plants to make their own food using sunlight.
