[YvonneM]

Leaves are green because they contain chlophyll which is used in photosynthesis
What is Photosynthesis? Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process

To expand, photosynthesis requires light, roots are undergroung so they don't receive light, don't partake in photosynthesis and do not contain the green pigment chlorophyll

They are white because they do not have chlorophyl like YvonneM described. They are also white because they are basically bare Vascular bundles. This is what contains the Xylem and Phloem which are two types of transport tissue which carry food (in the Phloem) and water (in the Xylem).

Yes to the whole photosynthesis light chlorophyll thing!
