#1. True or False? Oranges are actually green. They only turn orange if it gets cold, which causes the chlorophyll in their skins to break down.

True. Even when ripe, oranges are often bright green in colour. They only turn orange if the weather gets cold enough to cause the chlorophyll in their skins to break down.
