These leaves are found on the same tree, however, the top cross section is of a leaf in the lower canopy, which is relatively shaded. The other of the upper canopy, which is exposed to more sun. ENCER 40x (x.s.) Describe two differences between sun and shade leaves at the macroscopic (leaf) and two differences at the microscopic (cross section) scale and provide explanations for the differences observed in color (specific chlorophyll a vs. b enrichment and accessory pigments) and shape (leaf thickness and width). Note: You do not need to sketch out the leaf/slides.Consider a soil with the following properties: The water content at the permanent wilting point is 0 = 5 Vol.% The actual plant available water accounts for 3 Vol.% The water content at saturation is 0,-38 Vol.% The water content at a suction of 10 cm is 35 Vol.% a) What is the field capacity of your soil?

Biologists investigated the effect of the presence of aluminum ions on root tips of a variety of wheat. They removed 2-mm sections of the tips of roots. Half of the root tips were placed in a nutrient solution with aluminum ions, while the other half were placed in an identical nutrient solution without aluminum ions. The length of the root tips, in millimeters, was measured every hour for seven hours. The results are shown in the data table below.
