The key (for the host: fold this page back)
- C: protein. Pollinators get food, and the flowers get their pollen moved. Both sides win.
- C: North and South Carolina. They live in longleaf pine lands near the coast.
- A: about 35 years. Once it starts, a saguaro keeps making flowers for the rest of its life.
- B: carbon dioxide. The sugar is the plant's food, and oxygen is given off.
- B: the bristlecone pine. Some bristlecone pines are thousands of years old, so their rings record ancient weather.
- C: chlorophyll. It is the most common pigment in a leaf, which is why most leaves look green.
- B: humans. Fungi were counted as plants until the late 1960s, when they got their own kingdom.
- B: volume. This giant sequoia holds about 52,500 cubic feet of wood.
