The part of the cell that captures energy from sunlight and uses it to produce food for the cell is the chloroplast.

Here's why:

* Chloroplasts are organelles found in plant cells and some algae.

* They contain a green pigment called chlorophyll, which absorbs light energy from the sun.

* This energy is used to convert carbon dioxide and water into glucose (sugar) and oxygen through a process called photosynthesis.

* The glucose serves as food for the cell, providing it with energy.

So, chloroplasts are like tiny solar panels within plant cells, allowing them to harness the power of sunlight to create their own food.
