The organelle that allows plants to make their own food through photosynthesis is the chloroplast.

Here's why:

* Chloroplasts contain chlorophyll: This green pigment is essential for absorbing light energy from the sun, which is the first step in photosynthesis.

* Photosynthesis takes place within the chloroplast: The chloroplast has internal membranes and compartments where the reactions of photosynthesis occur. These reactions convert light energy, carbon dioxide, and water into glucose (sugar) and oxygen.

So, the chloroplast is the powerhouse of plant cells when it comes to food production!
