A new report explains why many Americans can't afford the average new car. Mar 16, 2014 at 3:30PM. Ford's F-150 is America's best-selling new vehicle. But at an average transaction price of close to $40,000, it's out of reach of many American households -- or should be, says a new report.
How to Calculate Leaf Surface Area. The rate of transpiration is measured as the amount of water lost/ square meter/ minute. Because water evaporates through the many stomata on the leaf surface, the rate of transpiration is directly related to the surface area. 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. 1  Lay the leaves to be measured on a 1-cm grid and trace their outlines. 2  Count the number of square centimeters.
Leaves-Dorsiventral. These leaves grow horizontally, so that the majority of photosynthetic cells are facing upwards and receiving light in the day for photosynthesis. The majority of stomata are found on the lower half so that transpiration does not increase during the day.Dorsiventral leaves can either be 1) simple, consisting of one leave or 2) compound, consisting of many leaves stemming from the same petiole.Please contribute to this project, if you have more information about this term feel free to edit this page.This page was last modified on 3 October 2005, at 21:16.This page has been accessed 8,933 times.
