Sagebrush Leaves
After removing the leaf hairs on big sagebrush leaves, scientists at PNNL used scanning electron microscopy to develop images showing the position and number of stoma and guard cells of the leaf surface. The number and size of stoma found of leaf surfaces of desert shrubs varies and controls the rate of water loss from plants. Understanding plant transpiration water loss is important to estimate plant water use and predict total water balance in contaminated environments. This image was taken by scientist Janelle Downs through a project in collaboration with Washington State University.
