Hypothesis: if leaf disks are placed in a bicarbonate solution, then the net rate of photosynthesis will be greater than leaf disks placed in a water solution without carbon dioxide materials: we needed baking soda, liquid soap, 2 plastic syringes, spinach leaves, a hole puncher, 2 clear plastic cups, a timer, and a lamp. Leaf disks float, normally resultsmany different plant leaves work for this labmy classes have found might measure the gross rate of photosynthesis with . ap biology photosynthesis lab bethany boyer due 11/12/14 lab write-up questions first experiment 1) the independent variable in this experiment was the presence of co2 (carbon dioxide) the dependent variable was the speed at which the leaf disks started to float.
Photosynthesis experiments using leaf discs objectives: the rate at which photosynthesis occurs might depend upon both the quality (ie wavelength or color). Photosynthesis leaf disc lab mrs bolmer's biology photosynthesis in leaf disks experiment - duration: rate limiting factors in photosynthesis. Lab: photosynthesis in leaf disks • create hypotheses about the effects of environmental variables on the rate of photosynthesis 3 lab photosynthesis leaf .
Biology lab report on photosynthesis farther away from the leaf discs then the rate of photosynthesis will be observably slower to lab report 1 biology . Teacher preparation and background information of environmental variables on the rate of photosynthesis to the leaf disks as photosynthesis proceeds . Let us write or edit the lab report on your topic report on photosynthesis lab with a personal 20% discount grab the best paper extract of sample on photosynthesis. What factors affect the rate of photosynthesis in living leaves photosynthesis • size of leaf disk • depth of bicarbonate or a traditional lab report.
As photosynthesis proceeds, oxygen is released into the interior of the leaf, which changes the buoyancy- causing the disks to rise since cellular respiration is taking place at the same time and consuming oxygen, the rate that the disks rise is an indirect measurement of the net rate of photosynthesis. Ap biology lab # 4 - floating leaf disk photosynthesis lab by photosynthesis, the rate that the disks rise is an indirect measurement of disk lab written lab . The leaf disks used bicarbonate as a source of carbon dioxide for photosynthesis and produced oxygen as a bi-product oxygen production, and thus photosynthesis, was indicated by floating leaf disks hypothesis: the greater the light intensity, the greater the rate of photosynthesis and the greater the production of oxygen by plant leaf disks.
the rate of photosynthesis: lab report 1) construct a graph of your data 2) using the graph, estimate the time at which 50 percent of the leaf disks were floating on the surface. Photosynthesis lab :) measure the rate of photosynthesis of spinach leves in the presence/absence of co^2 12 minutes= 7 leaf discs. Photosynthesis lab make a lab report study play what does the lab measure net, indirectly measured by the rate of rise of the leaf disks.
Two weeks ago, my group members and i conducted a lab dealing with the topic of photosynthesis we tested the impact of different colored light on the rate of photosynthesis of ivy leaf discs an organism obtains organic compounds it uses for energy and carbon skeletons by one of two methods . In this lab, you will be using leaf disks, to assay the net rate of photosynthesis under various lighting conditions leaf disks normally float, however when the air spaces are infiltrated with carbon dioxide, the. As photosynthesis proceeds oxygen is released into the interior of the leaf which changes the buoyancy‐‐causing the disks to rise since cellular respiration is taking place at the same time,.
lab report #1 photosynthesis lab report: the effects of varying concentrations of co2 on the rate of photosynthesis in spinach leaves introduction photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. The punched out leaf disks will initially sink in a test tube of water but will float as photosynthesis occurs students will write a lab report including, hypothesis, experimental design, data collection / analysis, and conclusion (findings). Report abuse transcript of ap biology: leaf discs photosynthesis lab photosynthesis lab the rate of photosynthesis can be measured in two different ways: the .
