Activities |
1. The apical distance of Branch type 1 was measured from the tip of the branch to the last leaf (Figure 1). The section of 15 cm from the tip of Branches type 2 was considered since its total apical distance was greater than 50 cm, involving a lot material. |
2. The leaves from each branch were removed from stems to measure the internodal distance (distance between the position of the leaves on each steam). |
3. To observe the leaves and their structures (veins and trichomes) monocular stereoscope (40X). |
4. The outline of all the leaves of each branch was drawn with pencil on paper millimeter and baking paper was well. |
5. To count the number of squares of 1mm occupied by the leaves draw of each branch |
6. To cut out the leaves that were drawn on the banking paper, put in the plastic bags identified with the marker pen. |
7. To weight a square of 5 cm × 5 cm (25 cm2) of banking paper to calculate the leaf area of each branch through the rule of three (the method of finding the fourth term in a proportion when three terms are given), using a precision balance (0.01 g). |
8. To weigh each group of leaves belonging to each branch, using a precision balance (0.01 g). |
9. To answer only the no. 3 and 6 listed in Table 2 after the practical activity. |
10. To perform extra activities at home to answer the others 10 questions (1 ? 2, 4 - 5, 7 - 12) listed in Table 2. |
