Chlorophyll (noun, “CHLOR-oh-fill”)

This is a word used to describe several kinds of green pigments in plants. They are often contained in structures called chloroplasts. These green pigments use sunlight to make energy out of carbon dioxide and water. In the process, they produce oxygen — something we all need to get by.
