Why are limes green?

Here's a breakdown:

* Chlorophyll is the green pigment that plants use to absorb sunlight for photosynthesis.

* Photosynthesis is the process by which plants convert sunlight into energy.

* Limes, like other fruits, start out green because they need to perform photosynthesis to grow and develop.

* As limes ripen, they may turn yellow or even slightly orange, but they don't lose all their chlorophyll. This means they can still photosynthesize even when they're ripe.

So, in short, limes are green because they contain chlorophyll, just like other green plants!
