Why are carrots orange?

In my botany class, we were discussing roots and the question came up on 
WHY do carrots (the part we eat of them) contain carotene?  Since they are  
underground, they don't need carotene as any kind of accessory pigment,
right?  Is there any evolutionary significance to this?  Is carotene a 
toxin to certain parasites?  I'm just a first year biology student and 
I've done a little bit of searching in the library for an answer if 
there  is one, with no success.  I would greatly appreciate your input.
