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 and increasing light intensity will have no effect, so the rate plateaus lower. The light intensity will be changed for it is the only variable used in the experiment though the temperature, watt of the bulb, amount of water, size of the plant and position of the clamp and stand. 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 essay photosynthesis and light-dependent reactions however, it is the energy from the red and blue light that are absorbed that is, thereby, able to be used to do photosynthesis photosynthesis and light intensity - 340 words the purpose of this lab is to determine which pigments in a plant support or effect. 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. During the photosynthesis, the light strength will increase when the rate of photosynthesis addition ( pang 2006 ) in my consequence, the distances from light strength are increased when the rate of photosynthesis lessenings, which mean when the light strength lessening, the rate of photosynthesis besides decreases. An investigation into the effect of light intensity on the rate of photosynthesis of canadian pondweed (elodea canadensis) 5 star(s) all green plants need to be able to make their own food. However, once the light intensity gets high enough, the rate won’t increase anymore because there will other factors that are limiting the rate of photosynthesis a limiting factor could be the amount of chlorophyll molecules that are absorbing the light.

The effect of light intensity and temperature on the rate of photosynthesis 2120 words | 9 pages 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. The consequence of light colour on the rate of photosynthesis to what extent does the coloring material of visible radiation have on the rate of photosynthesis oncabomba aquaticaworkss background cognition: we will write a custom essay sample on the effect of light colour on the rate of photosynthesis specifically for you for only $1638 $139/page. Summary: light intensity is a factor in the rate of photosynthesis, which is production of simple sugars from carbon dioxide and water causing the release of sugar and oxygen light is what causes photosynthesis to occur hence it stands to reason that the intensity and duration of light will affect. Light intensity also affects the rate of photosynthesis, which is demonstrated through the preliminary experiment i have carried out this involved taking a piece of pondweed and inserting it into the photosynthometer where the amount of o2 produced was measured. Higher the intensity of light will provide the plant with more light energy, whereas lower the intensity of light, there will be a lower quantity of light energy available the intensity of light will also affect the rate of photosynthesisthe third factor is carbon dioxide, this is a reactant in photosynthesis.

At a light intensity of 50 arbitrary units for the shade grown plant, and 150 arbitrary units for the light grown plant, the rate of change in co2 levels was a negative value (-15, -104) this implies that the net rate of photosynthesis was greater than the net rate of respiration. The essay above on impact the factors affecting rate of photosynthesis is among the many you will find online at wwwbestessayservicescom if you need assistance in writing essays term papers and other academic research at college or university level get in touch with us and we will help you. Aims i plan to investigate how different factors affect the rate of photosynthesis background information the rate of photosynthesis is affected by a number of factors including light levels, temperature, availability of water, and availability of nutrients. 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.

the effect of light intensity on the rate of photosynthesis essay At low light intensities, the limiting factor governing the rate of photosynthesis is the light intensity as the light intensity increases so does the rate but at high light intensities one or more other factors must be limiting, such as temperature or carbon dioxide supply.

Chlorophyll word equation for photosynthesis: light energy 6co + 6h o c h o + 6o 2 2 chlorophyll 12 6 2 my aim: my aim is to determine the effect of light intensity on the rate of photosynthesis. The effects of carbon dioxide on the rate of photosynthesis introduction: carbon dioxide is a necessary reactant in the process of photosynthesis this activity is designed to determine the effect, if any, of different amounts of carbon dioxide on the rate of photosynthesis. To farmers, understanding the factors affecting the rate of photosynthesis can assist in determining ways on how to increase the rate of photosynthesis for bountiful crop yields there are various factors that can affect the rate of photosynthesis like light intensity, temperature and carbon dioxide concentration.

To investigate the effect of light intensity on the rate of photosynthesis principle of design and assumptions it is known that light is required in the photochemical stage of photosynthesis. At 2% light intensity the rate of photophosphorylation, the production of atp by photosynthesis, was approximately 97% lower than in chloroplasts exposed to 100% light intensity (stroop and boyer 1987), supporting the hypothesis. Light intensity: the effect of this is that of a direct or linear relationship in which the photosynthesis rate increases with an increase in the intensity of light available this implies that the brighter the sunlight is the higher will be the rate of photosynthesis. The rate of photosynthesis is directly proportional to light intensity (kent, 2000) materials and methods in this experiment, a hydrilla sprigs, a beaker, test tube, funnel, water, box, and light source are needed.

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. 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.
