Investigates some of the extraordinary ways in which plants gain nutrition and protection by using their leaves, spines, stings, poisons and disappearing tricks. Examples featured include: cheese plants on the forest floor, the Costa Rican rainforest canopy; the mimosa, Venus fly traps, the pitcher plant (Nepenthes rajah) on Mount Kinabalu in Borneo, 4000-year-old bristle-cone pines in the White Mountains of California, and giant sequoias in the Sierra Nevada. Photosynthesis is explained and computer-generated electron microscopy images are used to reveal the intricate structure of a leaf and how chlorophyll is used in photosynthesis. Computer images are also used to show how a seventy-foot tall sycamore tree gets water to the leaves at the top of its growth.
