Question
Light that the chlorophyll-a pigment uses may be measured by the solar-induced fluorescence (650-850nm). This fluorescence caused by the sun and a plant's gross primary output are correlated linearly. Why does this reasoning shows that solar induced fluorescence can be used to infer net photosynthesis?

- One of the constants in the experiment was that the chloropyll content was measured every 48 hours. A True B Falsearrow_forwardAnthocyanins are another type of plant pigment that are purple or red. Say you run a chromatography experiment using the same setup as you did in this lab, and you find that anthocyanins do not move from the line of origin. Assuming the solvent traveled the same distance as in your experiment (D in Table 1 above), what is the Rf value of anthocyanin?arrow_forwardPhycobiliproteins are complex proteins in cyanobacteria that absorb light energy. There are three different kinds of phycobiliprotein molecules used to pass light to chlorophyll: phycoerythrin is responsible for capturing green light, phycocyanin is responsible for capturing orange-red light, and allophycocyanin is responsible for capturing red light. Since light can only penetrate to certain depths in oceans, phycobiliproteins capture the light available and pass it through various pathways of phycobiliproteins until the emitted light is red, which is absorbed by chlorophyll.

- Below are pictures of leaves from a Garry Oak tree (Quercus garryana). 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).
