Materials birch leaves (1 per pair of students) Stomatal density varies between monocots and dicots, between plant species, and between the underside and top side of the leaves on a plant.there are a number of ways to measure stomatal density. Using the same microscope, what is the density of stomata per mm2 based on the following counts?
Work Out How Many Of Sections Of Leaf Of This Size Would Make Up 1 Mm2.
• compare number of stomata present in older specimens and newer specimens; You can calculate this using the formula area = πr 2, when you have measured the true radius of the field of view ( r ). Ds = 375 / 3 = 125 (stomata/mm^2) example problem #2:
