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