Plastic drop-in screens like this are super easy to install. Because water evaporates through the many stomata on the leaf surface, the rate of transpiration is directly related to the surface area. In addition to performing photosynthesis, some plants have other highly specialized functions. For example, young spring leaves are light yellowish-green, but quickly lose the yellowish cast and darken with maturity. 5. Because of the complexities noted earlier, systematic attempts to construct global maps of surface albedos from satellite observations are just now being undertaken.

Leaves that emerge after summer rains tend to be reddish. To arrive at the rate of transpiration, therefore, you must calculate the leaf surface area of each plant: Because most stomata are found in the lower epidermis, you will determine that surface area. We have moved all content for this concept to for better organization. Ozone symptoms usually occur between the veins on the upper leaf surface of older and middle-aged leaves, but may also involve both leaf surfaces (bifacial) for some species.
