Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities.
How to Take a Eucalyptus Cutting. Juvenile eucalyptus trees root better than adult trees. Eucalyptus (Eucalyptus spp.), are ornamental trees, that often grow to heights of 80 to 120 feet. Native to Australia, eucalyptus grow in the warmer climates of U.S. Department of Agriculture plant hardiness zones 6 through 11, depending upon the species. They're easy to propagate from seed, but you can also clone them through rooted cuttings taken from juvenile trees.
What They Did. The researchers compared eucalyptus tree leaves at gold prospecting sites in Western Australia with leaves from trees 2,625 feet (800 meters) away. They also grew eucalyptus trees in greenhouses with potting soil dosed with gold particles, as well as in normal potting soil without gold. What They Found.
