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 final results demonstrated that in the co2 solution, photosynthesis went on normally in the first experiment however in the water solution, none of the spinach chads produced o2 and floated, determining that co2 is needed in order for photosynthesis to take place. Ap biology lab four: plant pigments and photosynthesis observing mitosis ap biology lab #4 plant pigments and photosynthesis lab report background: (part a)paper chromatography is a useful technique for separating and the plant with the most accessory pigments was the spinach their role in photosynthesis is to absorb specific.
The rates of photosynthesis in a bicarbonate solution will be compared to the rate in water while the rate of photosynthesis in the spinach leaves at 18 degrees celsius will be compared to the rate at 25 degrees celsius.
The purpose of doing this lab was to observe how different pigments in leaves use different wavelengths of visible light for photosynthesis spinach extract was separated by paper chromatography into: chlorophyll a, chlorophyll b, xanthophyll, beta carotene and also total pigment. Errors could have occurred because of damaged spinach, inaccurate reading, fingerprints on the cuvettes, or erroneous measurements or erroneous measurements related interests documents similar to ap biology photosynthesis lab report skip carousel carousel previous carousel next chromatography and photosynthesis uploaded by.

The disks in the 4% solution lagged behind to reach 10 floating spinach disks a minute later while only 9 disks in the 2% floated by the end of the 10 minutes without a source of carbon dioxide for photosynthesis, the 0% solution was not able to produce any floating disks. Photosynthesis in leaf disks teacher preparation and background information general information: safety: (spinach, ivy, pansy, other of your choosing) another factor you could test to determine its affect on photosynthesis set up a lab notebook page that lists your hypothesis, materials, procedures, data charts and conclusions. Ib biology higher level lab report title: investigate the effects of sodium bicarbonate and light intensity on the rate of photosynthesis of green spinach leaves through the observation of floating leaf discs.
Ap biology lab four: plant pigments and photosynthesis the purpose of this lab is to separate and identify pigments and other molecules within plant cells by a process called chromatography we will also be measuring the rate of photosynthesis in isolated chloroplasts. Photosynthesis lab report abstract: photosynthesis is a natural process all plants undergo to create energy from light in a plant, photosynthesis creates oxygen as a byproduct, and cellular respiration uses oxygen to make water.
