Effect light intensity on photsynthesis elodea
The concentration of water, carbon dioxide, the temperature and the light intensity are the most common environmental factors to affect photosynthesis (lincoln 2010) so the aim of this scientific experiment is to investigate the effects of light intensity on the rate of photosynthesis. Investigating the rate of photosynthesis this is an example of a common experiment used to investigate light intensity and the rate of photosynthesis. Lab 2: experiments in carbohydrates photosynthesis – light intensity and color effects photosynthesis is as the heart of almost all terrestrial ecosystems it the process evolved in plants, to harness the energy from the sun and to use it to fix carbon the effect of colored light on the rate of photosynthesis in elodea 1 repeat the same. In general, plants need food in order to grow the process by which plants make their own food is called photosynthesis we can determine if light affects the growth of an elodea plant by finding.
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. 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. The intensity of light directly affects the rate of photosynthesis (bidwell, 1979) graphs show that the higher the intensity, the higher rate of photosynthesis the intensity in this experiment was increased by moving the tube closer to the light.
Does light intensity have an effect on elodea photosynthesis the effects of light intensity on the rate of photosynthesis aim: to investigate the effects of light intensity on photosynthesisbackground: photosynthesis is a process that plants undergo to produce glucose the plant then uses the glucose to produce energy which the plant needs to sustain life. In my prac group, we studied the effect of temperature on the productivity of photosynthesis in an elodea section (roughly around 10cm long) at a temperature of 50°c the next step is to try to establish the effect of changing the light intensity on the rate of photosynthesis move the lamp closer to the plant – to the next position for. Photosynthesis is the process by which green plants and certain other organisms transform light into chemical energy in green plants, light energy is captured by an investigation into the effect of light intensity on the rate of photosynthesis of canadian pondweed (elodea canadensis.
An increase in temperature with high light intensity increases the rate of photosynthesis therefore this can cause the results to be unreliable measuring the temperature with the thermometer could have been incorrect because the thermometer was placed in different area each time. Besides the light factor i also decided to put a 100 watt lamp above each plant so i get a high light intensity to speed up the rate of photosynthesis aim: the purpose of this experiment is to find out under what wavelength (different colour of light) the elodea plants are able to grow and photosynthesise the best. Conclusion: change in light intensity causes a change in the rate of photosynthesis graph the results placing light intensity on the x-axis ^intensity may also be changed by changing the wattage of the bulb. 6co + 6h o ® c h o + 12o (in the presence of light energy and chlorophyll) aim- the aim of the experiment is to determine what effect light intensity has upon the rate of photosynthesis of canadian pondweed (elodea.
Effect light intensity on photsynthesis elodea
// provide alternate content for browsers that do not support scripting // or for those that have scripting disabled this virtual experiments require adobe flash. The effects of light intensity on the rate of photosynthesis of the aquatic plant, elodea were tested two light intensities, time, and distance was measured throughout this experiment two light intensities, time, and distance was measured throughout this experiment. - determining the effect of light intensity on photosynthesis aim in this experiment, i intend to alter the light intensity and measure its effect on photosynthesis through the production of oxygen introduction photosynthesis is the process by which green plants provide a source of energy for respiration. D change one factor that may affect the rate of photosynthesis, keeping all other factors the same as far as possible (refer to teaching notes) light intensity or distance of the elodea from the lamp colour of light coloured filters can be used, but these will affect light intensity by different amounts depending on the colour.
- The mass transfer rate of 14 c-sucrose translocation from sugar beet (beta vulgaris, l) leaves was measured over a range of net photosynthesis rates from 0 to 60 milligrams of co 2 decimeters −2 hour −1 under varying conditions of light intensity, co 2 concentration, and o 2 concentration.
- Aim: to determine whether factors such as light intensity and concentration of sodium hydrogen carbonate (nahco3) will affect the rate of photosynthesis in the water plant, elodea hypothesis: the higher the light intensity the faster the rate of photosynthesis as this provides more energy available for plants photosynthesis to take place.
The elodea produced oxygen through photosynthesis the group's hypothesis was, if the percentage of dissolved oxygen increases, then the levels of carbon dioxide will decrease we used three different amounts of baking soda: 0 grams, 50 grams, and 100 grams. The effects of light intensity on the rate of photosynthesis in elodea free essay, term paper and book report the effects of light intensity on the rate of photosynthesis in elodea _____ aim i aim to investigate the effects of the quantity of light and thus the light intensity on the rate of photosynthesis in elodea. Variables independent variable: intensity of light to elodea (1watts and 3watts per gallon) dependent variable: rate of photosynthesis (amount of oxygen produced or carbon dioxide used up.
