Red Strawberry

Hi,
as the fruit matures, just before it is ready to drop off, the strawberry produces sugar, (this process is the same in autaum leafs.) This reacts with the strawberry turing the strawberry red, this is why we eat strawberrys when they are red.

A strawberry is red because it reflects off the red light. It absorbs all the colors besides red that's why to us it looks red.
