Sketch the following on a separate sheet of paper (to be cut and pasted into lab book for part B Label the following: Vascular bundle Xylem Phloem Epidermis Parenchyma Collenchyma Sclerenchyma Pith

Water evaporates from stomates Water in the pipet moves downward

Leaf Surface Area: Leaf Tracing Each square of four blocks = 1cm 2 Total surface area = total number 4

Leaf Surface Area: Leaf Massing Mass a 1cm 2 section Mass x 10,000 = mass/m 2 Total Mass of Leaves (grams) = Leaf Surface Area g/m 2

Water Lost per m 2 = Water loss at each reading (mL) Leaf surface area (m 2)
