Multiple Choice

The wooly plant of the Himalayas has adapted to the low temperatures of the alpine zone by growing dense pubescence that provides thermal insulation. What tradeoff occurs because of this adaptation?

A) Reduced radiation at the leaf surface and lower photosynthetic rates
B) Increased radiative warming because of increased reflection from the white hairs
C) Increased water loss because of a thicker boundary layer around leaf
D) Increased daily thermal amplitude because of thicker boundary layer
