1. Uneven blotches and crinkly patches are on the leaf surface. 2. And many herbs spew essential oils into the air when their leaf surface is brushed, scenting the atmosphere with perfume. 3. Compulsive neatening reduces carbohydrate production because sunlight cannot get to all the leaf surfaces. 4. Even with a sharp blade, the loss of leaf surface means reduced photosynthesis and reduced ability to take up water. 5. Exposing less leaf surface to the sun reduces the amount of moisture lost through transpiration. 6. In either case, success depends on covering every inch of leaf surface, including the undersides. 7. Signs of the latter are half-inch black spots surrounded by a fringe on the upper leaf surface. 8. To protect themselves from too much water evaporation, their leaf surface is small and often plump. 9. With millions of the bacteria on a single leaf, water will freeze and spread easily on the leaf surface. 10. In a way, nature has been helping it withstand open situations by not extending a broad expanse of leaf surface for the sun to shine and concentrate on. |
