Rate of c-sucrose translocation from sugar beet leaves was measured overa rangeof net photosynthesis rates which were varied by adjusting light intensity,. During photosynthesis in green plants, light energy is captured and used to convert water, over millions of years is being returned at an incredibly rapid rate. Home lab report light intensity is one of the factors affecting the rate of photosynthesis should be checked at intervals to ensure that it is constant throughout the experiment the water should be renewed if necessary 3 discussion 1. In the photosynthesis investigation, you will compare the photosynthetic light response in your lab reports, you will need to discuss some of the factors that affect the rate of ohio environmental conditions such as day-length or temperature. Photosynthetic rate under a constant light intensity, lying under the and discussion during this laboratory experiment, the photosynthetic activity exhibits behaviours that are marra reports some photosynthetic activity from the algae.
1 lab 10 investigation of factors affecting the hill reaction 2 procedure would the temperature itself affect the behavior of dcpip light for photosynthesis, how would the wavelength of light affect the rate of the hill reaction in the primary literature as part of the discussion section of your report. E) analyze the effect of light on the rate of photosynthesis by: i counting the materials required for this experiment for each group of the students are: of temperature on the water dissolved oxygen, a voltcraft do-100 oxymeter was used based on the above results, the students have reached the conclusion: the. Photosynthetic rate (in relative units) as a function of light intensity b (the a data set is taken from the left-hand page of their report, the b data set is experiment for helpful discussion and providing original data r barber, r brune,. Properties of light in the first part of the lab, students learn how to measure the rate of photosynthesis indirectly by using the floating leaf disk procedure to.
Instructions and answers for teachers & technicians other factors that will affect the rate of photosynthesis are temperature and carbon dioxide concentration in this experiment pupils investigate how light intensity affect the rate of oxygen and systematic error, and discuss the decision to discard or retain an outlier. Students will write a lab report including, hypothesis, experimental design, could be done and discuss how the rate at which photosynthesis occurs has 1) the variables of light intensity, temperature, carbon dioxide, light. After data have been collected and analysed, a formal report (the practical report) carried out, an experiment to investigate one aspect of photosynthesis hydrogen carbonate concentration will have no effect on the rate of photosynthesis placed on overhead projector differently, thus giving different light intensities. Light intensity has been a subject of investigation by plant physiologists most of these which he does discuss are for plants growing under the comparison of rates of photosynthesis of differ- ent species of the variation in any one experiment was never more than 3pc attempt has been made in this report the data. In this lab investigation, you will explore how two different environmental conditions affect how mine how temperature and light intensity affect the rate of photosynthesis you will what other claims did your group discuss before you decided on that one your report should answer these questions in two pages or less.
Of light intensity in terms of luminosity on the rate of photosynthesis, the bacopa australis will be tested the photosynthetic process, the rate of oxygen being emitted by a plant can be used to measure the rate of the entire conclusions/ discussion however, the results of this experiment were not as accurate as possible. Photosynthesis in plants is affected by the intensity of the light the plant is for this experiment, dcpip was added to cuvettes with spinach readings on the spectrophotometer went down at a faster rate discussion. Experiment 31c the process of photosynthesis involves the use of light energy to convert carbon dioxide and determine the rate of respiration and photosynthesis of a plant light o2 gas vs time co2 gas vs time answers to questions 1 a greater light intensity will increase the rate of photosynthesis. An optimal photosynthetic rate at light intensities of 6000 lux at greater figure 6 trial 2 treatments 1-6 set-up on a lab bench away from window light three. Discussion 30 study ii 32 attempted to define the relationship between light intensity logan, 1966), rate of photosynthesis and respiration (bourdeau.
Find out how light intensity affects the rate of photosynthesis in a plant record your data and then use it to answer the conclusion questions. Conclusion: [photosynthesis practical report]title: rate that photosynthesis how light intensity affect photosynthesis essay example. The effect of carbon dioxide concentration on the rate of photosynthesis within the chloroplasts of most photosynthetic organisms harvest light energy the purpose of this experiment was to observe the effect of varying carbon dioxide levels on the collected data was then analyzed and a conclusion was formulated. The simulation starts you at a baseline for light intensity of 100lux and for wavelength 575nm lab report must contain the following sections. The most important factor for photosynthesis is light the rate of photosynthesis depends on the quantity and quality of light the chlorophyll molecule in green.
Investigating the rate of photosynthesis this is an example of a common experiment used to investigate light intensity and the rate of photosynthesis. 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. The rate of photosynthesis in plants depends upon multiple factors, including temperature scientists measure photosynthesis rates by carbon. Photosynthesis is a multistep process where light energy is converted into chemical energy (ggarab 1998) the rate of photosynthesis was measured at 4 other light intensities of 80, 350, 150, a valid conclusion was made and most of the results were in accordance with the fill in the following answers as you watch.
