50 sun leaves and 50 shade leaves were placed labeled on the benchmark ready for different analyses. Each of the leaves was analyzed to establish its characteristics. A thread string was stretched lengthwise from one end of the leaf through the center to the other end and then tracing the thread string on the ruler to establish the leaf length. Similarly, the thread was traced across the leaf and then the measurements were taken by tracing it on the ruler. Afterward, the thread was wound around the leaf, and then tracing the length of the wound thread was on the ruler to get the perimeter of the leaf. The area of each leaf was determined by careful tracing its shape on square graphical paper and using the least square method calculating the surface area of the leaf as well as the leaf sinus area. Finally, each of the leaves was placed on a top-loading balance and the reading was taken for each leaf and recorded. The data was tabulated as shown in table 3 and analyzed using descriptive data analysis.
