Lab 5 photosynthesis: why do temperature and light intensity affect the rate of photosynthesis in plants introduction you have learned that green plants have the ability to produce their own supply of sugar through the process of photosynthesis photosynthesis is a complex chemical process in which green plants. Photosynthetic rate under a constant light intensity, lying under the photo- inhibition level, may be described in during this laboratory experiment, the photosynthetic activity exhibits behaviours that are clearly unexpected from troduction of a finite characteristic time of evolution t in the model, affects mainly the response. The research aspect of this science fair project is to assess how light intensity affects the rate at which photosynthesis occurs and the rate of oxygen production to aid students in their practical work, a set of simple experiments are described and explained along with a comprehensive further reading list is included. B14c describe photosynthesis as an endothermic reaction b14d describe experiments to investigate photosynthesis b14e explain the effect of temperature, light intensity and carbon dioxide concentration on the rate of photosynthesis b14f explain the interaction of these factors in limiting the rate of photosynthesis. There are several factors affecting photosynthesis- its rate and efficiency let's look at these factors affecting photosynthesis and understand how they affect however, the light becomes a limiting factor in low intensity because no matter how much water or co2 is present, without light photosynthesis cannot occur at high.
1) the variables of light intensity, temperature, carbon dioxide, light quality all influence the rate of photosynthesis 2) photosynthesis the lab could be used in a unit on, the scientific method, a photosynthetic unit or in a unit on environmental problems (global climate change and its affect on plants) subject: biology:cell. Mesophyll cell size in affecting rates of apparent photosynthesis per unit leaf area the use and validity of a warburg for this light source 1000 ft-candle = 0070 cal/cm^/min in the spectral region 400—720 mp during the experiment, the effects of the fifteen environments were not examined at random with time, as the. Nowadays in schools, new experiments and new pedagogical approaches for 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 white light (a) chlorophyll is green, different colours of light (ie, different wavelengths) affect.
Factors affecting photosynthesis three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature rate of photosynthesis plotted against light intensity the rate begins to slow as the light light intensity without enough light, a plant cannot photosynthesise very quickly, even if. Carbon dioxide concentration will directly affect the rate of photosynthesis as it is used in the photosynthesis reaction it is also easy to change the amount of carbon dioxide that the plant receives light is also directly used in the photosynthesis reaction and is easy to change in normal lab conditions. To the next comment, hypothesis i don't know what that experiment was but the ones that are currently on ask will online are: – light intensity effecting rate of photosynthesis – rate of reaction between sodium sulphate and hydrochloric acid – height of holly leaves affect prickliness – investigating human power.
Light intensity is one of the factors affecting the rate of photosynthesis other factors are and note the temperature the beaker of water acts as a heat filter or heat shield, so its temperature should be checked at intervals to ensure that it is constant throughout the experiment the water should be renewed if necessary 3. Biology experiment: photosynthesis the effect of light intensity on inelodea's rate of photosynthesis aim: investigating the effect of increasing light intensity on rate of photosynthesis of inelodea (water plant) light intensity is manipulated by changing the distance of the beakers from the lamp rate of photosynthesis is.
#41 effect of light intensity on the rate of photosynthesis plants need light energy to make the chemical energy needed to create carbohydrates increasing the light intensity will boost the speed of photosynthesis however, at high light intensities the rate becomes constant picture experiment place a pond weed elodea. The yellow leaves were more affected by light intensity, the green thought desirable to repeat the experiments of willsttttter and stoll taken as typical the rate of photosynthesis increases first rapidly with increasing light intensity, then more slowly at very high light intensities the rate of the process is practically.
Learn how plants make food using photosynthesis and how leaves adapt to do this with bbc bitesize ks3 science this is an example of a common experiment used to investigate light intensity and the rate of photosynthesis this should to use pondweed to see how light intensity affects the rate of photosynthesis. Band - pass filters during the expcrimerlts in chapter 2, the problem arose a s to what the co compensation point really represented 2 what arc the actual rates of co exchange at the compensation 2 point and arc they affected by light intensity and 0 2 conccntr,tj on to answer thi s question, experiment s using.
Objectives generate hypotheses about rates of photosynthesis in response to increasing light intensity about four plant species test those hypotheses by plotting light intensity versus photosynthesis rates for four plant species lab 5 overview i formulate hypotheses about photosynthesis rates in plants. Recovery experiments indicate that, at least at the higher intensities, there is an injury which becomes more severe with time several such experiments are illustrated in fig 3 curve a shows photosynthesis in 1,000 f-c, an intensity somewhat below the so called light saturation and at which no depression in rate has ever. Free essay: biology coursework ¡v does the light intensity affect the rate of photosynthesis the investigation in this experiment i will investigate the. Limiting factors the main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature in any given situation any one of these may become a limiting factor, in other words the factors that directly affects the rate at which photosynthesis can take place masking the effects of the other.
Photosynthesis will increase there are many things which can affect the photosynthesis of a plant such as light intensity, temperature and carbon dioxide levels there will be a maximum level of photosynthesis during the experiment it is called a limiting factor this factor will prevent the rate of photosynthesis from rising. Leaving cert biology photosynthesis experiment. General overview: in this lab, students will make hypotheses about how different variables (such as light intensity, water ph, and co2 availability) might affect the rate of photosynthesis in elodea plants, and then students will carry out a series of 2-minute experiments under different conditions to test their hypotheses. Studies on many woody species have shown that height growth, dry weight production and distribution (gordon, 1969 logan, 1966), rate of photosynthesis and respiration (bourdeau and laverick, 1958 loach, 1967), and chlorophyll content (zelawski and kinelska, 1967) are all affected by shading shading also caused.
