This experiment will look at the affect of light intensity on the rate of photosynthesis on elodea plants the rate of photosynthesis is determined by the number of bubbles formed by the elodea plants. Ap biology investigation on photosynthesis includes background information and instructions for using spinach leaf disks, light, and baking soda to measure the rate of photosynthesis specific instructions are included for measuring the rate of photosynthesis in relation to light and carbon availability. From the table, it is clear that light intensity on the pondweed effects the time taken for the hydrogen carbonate indicator to go from red to purple as high light intensity produced an average of 278 minutes where low intensity produced an average of 35 minutes.
During the experiment, the effect of light intensity on the electron transport chain was measured by the substitution of nadph with dpip nadph is an electron acceptor in photosynthesis and dpip is used as a substitute electron acceptor used for dye reduction in experiments. Introduction real world connections light intensity is a factor in the rate of photosynthesis, which is the production of simple sugars from carbon dioxide and water, causing the release of sugar and oxygen. Rate of photosynthesis = _____1_____ taken for the bicarbonate indicator to change from deep red to dark purple (min) where rate of photosynthesis is 1 over time taken for the bicarbonate indicator to change from deep red to dark purple0222 00151 0 the time taken for the brown bicarbonate indicator to change from deep red to dark purple at.
This lab tests the coupled reactions of photosynthesis and cellular respiration photosynthesis is the process by which plant cells take in water, carbon dioxide, and light energy to produce glucose. Published: mon, 5 dec 2016 the purpose of this lab was to see separate and identify the pigments of spinach cells through the use of paper chromatography through this lab, one can understand the rate of photosynthesis and absorbency rate of chloroplasts in different light intensities. Photosynthesis lab report for only $1390/page the rate of photosynthesis of a plant exposed solely to either room or lamp light controlled variables: amount of light the plant receives, the intensity of the light, type of light bulb, the amount of time the plant is exposed to one type of light, the type of plant, health of plant, age of.
The reason that light intensity does affect the rate of photosynthesis is because as light, and therefore energy, falls on the chloroplasts in a leaf, it is trapped by the chlorophyll, which then makes the energy available for chemical reactions in the plant. Photosynthesis is the process of trapping light energy and converting it into forms of chemical energy that are then used to drive the building of carbohydrates the vast majority of living. The interplant distance that produces the greatest rate of areal photosynthesis (mg c per m2 per day), and thus the largest areal yield, is influenced by several factors, such as temperature extremes, light intensities and water availability. Discovering photosynthesis by experiments 6 this experiment tests the influence both of the light colour (red, blue, green, and white) and of the light intensity on the photosynthesis rate.
Numerical simulations and discussion in order to test the validity of our hypothesis, we compare the results provided by the model with the data generated by marra  during a laboratory simulation study of the effect of mean and short-term variations in light intensity on the photosynthetic rate of a marine phytoplankter belonging to the. - the relationship between light intensity and the rate of photosynthesis investigate the relationship between light intensity and the rate of photosynthesis photosynthesis is important because animals eat food, as it is a source of energy. This activity is a lab where students design an experiment to test the rate of photosynthesis students will analyze data,write a report using the scientific method, and apply results to current environmental issues. Lab: exploring the rate of photosynthesis photosynthesis is the process by which plants take carbon dioxide from the atmosphere, add water, and use the energy of sunlight to produce sugar photosynthesis occurs in the chloroplast, an organelle in plant cells that contains the molecule chlorophyll. Light intensity and photosynthesis lab report group members: maritoni valencia, sangita tamang, ryutaro seiki and mao introduction: light intensity is one of the factors affecting the rate of photosynthesis other factors are concentration of carbon dioxide, temperature and to a lesser degree, water.
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 the speed or rate of both these processes combined is called “net photosynthesis” we wanted to see if light intensity affected the rate of photosynthesis. Photosynthesis lab report essay sample photosynthesis is a food making process for algae and plants the photosynthesis process rate varies from different wavelengths and intensities of light. Variables (such as light intensity, water ph, and co 2 availability) might affect the rate of discussion: as a class, students will report their results and will discuss how each of the variables affected the rate of photosynthesis further discussion questions are: what ecological factors affect the various variables we observed as. Light reactions of photosynthesis laboratory 7 1 laboratory 7: has its maximum intensity in the middle of the visible spectrum, near 530 nm (yellow light) chlorophyll does not laboratory 7: light reactions 8 lab summary please include the following in your lab summary.
When light intensity increases, the rate at which photosynthesis occurs increases as well outdoor plants photosynthesize faster on a sunny day as opposed to a cloudy day (lee, 2003) temperature is another factor that affects the rate at which photosynthesis occurs. Your lab team will test all three levels of light intensity, using 100 w light bulbs we will combine the data from all lab teams for the data analysis and, ultimately, the laboratory report. Factors affecting the rate of photosynthesis in this investigation, you will measure the effect of light intensity, colour of light, lab report is hand written presents some information in logical order spelling, grammar, and si usage need some improvement. Photosynthesis lab report 1791 words | 8 pages abstract photosynthesis is a food making process for algae and plants the photosynthesis process rate varies from different wavelengths and intensities of light.
Discussion discuss the following questions with your lab partners and write down your conclusions 1) photosynthesis requires the plant to take in gases such as carbon dioxide and release gases such as oxygen. 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. The rate increases at a steady rate as the light intensity increases until near the end of each line where the rate decreases this is either because the photosynthesis reaction has reached it’s maximum rate of reaction or another factor is limiting the rate. Photosynthesis and cellular respiration nina r mccray may 5, 2015 biology lab (scie207-1502-a-07) ladonna mccowan-ferrier photosynthesis and cellular respiration lab report introduction this is an investigation of the effect of the intensity of light (photosynthesis) have on the rate of cellular respiration (measured as the number of.
