Best answer: light intenstity is a factor which can limit the rate of photosynthesis at low light intensities, if the light intensity is increased, the rate of photosynthesis increases this is because light excites chlorophyll molecules, providing the energy for the production of carbohydrates. Assuming that either the light history has no effect on the photosynthetic rate (figures 5a-5b) or the photo-inhibition effects on photosynthesis are negligible (figures 6a-6b. Low light intensity lowers the rate of photosynthesis as the intensity is increased the rate also increases however, after reaching an intensity of 10,000 lux (lux is the unit for measuring light intensity) there is no effect on the rate. Lab: what affects the rate of photosynthesis duration: 45 min class size: up to 32 students general overview: in this lab, students will make hypotheses about how different variables (such as light intensity, water ph, and co 2 availability) might affect the rate of. There are five matters that affect the rate of photosynthesis: light intensity, temperature, co2, water, and the color of light in general in this experiment, the team aims to manipulate the color of light and control the following variables: co2, water, and temperature.
1) the variables of light intensity, temperature, carbon dioxide, light quality all influence the rate of photosynthesis 2) photosynthesis requires carbon dioxide to furnish the carbon required to make glucose. Effect of light intensity on the rate of photosynthesis light intensity is one of the factors affecting the rate of photosynthesis other factors are concentration of carbon dioxide, temperature and to a. Simple experiments carried out by scientists shows that the rate of photosynthesis is critically dependent upon variables such as temperature, ph and intensity of light the photosynthetic rate is usually measured indirectly by detecting the amount of carbon dioxide released by plants. Keeping the light intensity the same means it will have no additional effect on the rate of photosynthesis a change of light intensity would result in a change of photosynthesis rate control.
Light intensity has a very large effect on the rate of photosynthesis in most cases, the more light the faster photosynthesis occurs however, at some point there's a limit that the rate of photosynthesis cannot increase above. By: sarah boden, makayla spillman, mackenzie bissell does light affect the rate of photosynthesis 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. #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. 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.
Gradually the rate falls and at a certain light intensity, the rate of photosynthesis remain constant (from point b to point c on the graph) hence, a rise in light intensity has no affect on the rate of photosynthesis as the other factors such as temperature and carbon dioxide become limiting. 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. - 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.
Many external and internal factors affect the rate of photosynthesis the external or environmental factors at:a light intensity, carbon dioxide concentration and temperature. The rate of photosynthesis increases linearly with increasing light intensity (from point a to b on the graph) gradually the rate falls of and at a certain light intensity the rate of photosynthesis stay constant (from point b to c on the graph. I want to find out if light intensity has any effect on the rate of photosynthesis i want to know if the intensity of light is high, then will the rate of photosynthesis will be faster further investigation is to find out various light intensities and the rate of photosynthesis by using coloured light filters.
Abstract using an open and a closed system of gas analysis, it was found that co 2 evolution in light and in darkness from plant leaves (sunflower, soybean, watermelon, eggplant, and jackbean) have a different response to temperature while the rate of co 2 evolution in light increased with increasing temperature from 17 to 35° and then declined, the rate of co 2 evolution in darkness. The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration in other words the factors that directly affects the rate at which photosynthesis can take place masking the effects of the other factors and increasing light intensity will have no effect, so the rate plateaus. The effect of light intensity and temperature on the rate of photosynthesis - the effect of light intensity and temperature on the rate of photosynthesis aim the aim of my experiment is to determine whether intensity of light and temperature would affect the rate of photosynthesis in a plant.
