- Briefly describe the pigments used in photosynthesis, where these pigments are located in the plant, and what these pigments do. Define both absorption spectrum and action spectrum, and describe the purpose of using a spectrophotometer to determine the absorption spectrum and how that correlates to the action spectrum. Be sure to discuss how the spectrophotometer allows the identification of the pigment solutions.Describe the light reaction of photosynthesis. Be sure to include its location.Think of a metaphor or analogy of the light-dependent reactions similar to the “construction analogy”. Make sure to label your diagram and provide a ten-sentence summary that explains your analogy.

H20 ATP 02 NADP+ NADPH H+ ADP Reset 2018 McGraw-HEducationB) Describe the mechanisms employed by two types of plants to minimize photorespiration and ensure that the CC is carried out even when environmental conditions are not in their favor. Be sure to identify 1) the type of plant, 2) its natural environment and how it affects the plant's ability to perform the CC, and 3) how it has adapted itself to minimize photorespiration. 4Discuss other morphological differences between sunny and shady set-ups of mung bean in relation to phototropic response of plants.

- using a 14CO2 fixation assimilation method,a plant is found to be fixing carbon at a rate of 140mgh-1 .dm-2 leaf area in the sunlight. In darkness the same plant is losing 30mgh-1.dm-2 . Calculate the photosynthetic capacity of the plant and state with reasons to which photosynthetic type the plant belongsRubisco can bind with CO2 or 02. When it binds with O2, it "wastes" some of the energy captured from the sun. This reaction is photorespiration and is favored at high temperatures and low CO2:02 ratios. Which of the following strategies should limit photorespiration (select all that apply). Keep stomata closed. Keep stomata open. Physically separate the light and light-independent reactions. Temporally separate CO2 uptake and fixation.In hot, dry climates, plants have evolved mechanisms to avoid photorespiration. Which of the following is FALSE Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a b с d e C3 plants have no mechanism to avoid photorespiration C4 plants reduce photorespiration by separating the light reaction in the mesophyll cells from the light- independent reaction in the bundle-sheath cells CAM plants minimize photorespiration by collecting and storing CO2 at night and keeping their stomata closed during the day C4 plants include corn, sugarcane, and many grasses CAM plants can undergo photophosphorylation in the absence of sunlight Open in Readir
