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. 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. The effect of light colour and intensity on the rate of photosynthesis essay extraction this easy science project shows simple and efficient method of chlorophyll extraction from a plant - the effect of light colour and intensity on the rate of photosynthesis essay introduction. The effects of different wavelengths of light on the rate of photosynthesis introduction this experiment was performed to investigate the effects of different wavelengths of light on the rate of photosynthesis.

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. An investigation on the effects of light intensity on photosynthesis investigate how light intensity affects the rate of photosynthesis in pondweed the rate of photosynthesis will be measured by the number of bubbles given off (considering that oxygen is produced as a waste gas during photosynthesis. The rate of photosynthesis increases linearly, or is directly proportional to the intensity of light further increase in light intensity makes an increase in the rate of photosynthesis less and less pronounced, and finally stops when the illumination reaches a certain level of 10,000 lux. Most of the time, when the intensity of light is high, you will get a a greater rate of photosynthesis but, this rate has a limit, and once that limit is hit you can't increase the rate past that limit.
Factors affecting photosynthesis by understanding the factors that affect photosynthesis, one can better understand the rate of the process light: without light, a plant cannot photosynthesize very quickly, regardless of whether there are water and co 2 or not. 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. 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. 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. How does light intensity and carbon dioxide levels affect photosynthesis rate phaladi phaladi 201102379 department of mathematics and science education university of botswana plants, through the use of chlorophyll (green pigment in plants) that traps light can generate 'food' by combining carbon dioxide in the air and water.
The theory behind why the rate of photosynthesis in the papaya leaf discs decreases as the distance from the lamp increases is because by having the papaya discs further away from the lamp, the light intensity (controlled variable) is less direct and rorer. Effects of wavelength and light intensity on photosynthetic activity the photosynthetic process of eukaryotes revolves around chlorophyll, the substance that give plants their green color plants convert light energy into chemical energy by means of photosynthesis. Photosynthesis at 25 c, high irradiance, 25% o 2 and atmospheric levels of co 2 was about 80% of the co 2-saturated rate, suggesting that co 2 can be rate-limiting even without o 2 inhibition of photosynthesis. Aim the aim of my experiment is to find out how light intensity affects the rate of photosynthesis prediction i predict that as the light intensity increases that the rate of photosynthesis will increase in proportion, so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant.
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 will have an effect on plant growth - investigting the effect of light intensity on photosynthesis essay introduction with an increase in light intensity there will be plant growth at a faster rate in comparison to when the light intensity is low where plant growth is limited and will take place slowly. 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. Affect the rate of photosynthesis the investigation in this experiment i will investigate the affect in which the light intensity will have on a plants photosynthesis process this will be done by measuring the bubbles of oxygen and having a bulb for the light intensity variable.
Effects of light intensity on the rate of photosynthesis discuss the symbolism of light in the play, particularly the image of the light bulb it can be argued that scene 9 in which mitch forces blanche under the light bulb is the climax of the play. When light intensity increases, the rate at which photosynthesis occurs increases as well outdoor plants photosynthesize faster on a sunny day as opposed to a cloudy day (lee, 2003) temperature is another factor that affects the rate at which photosynthesis occurs. Effect of light intensity on photosynthesis design/carry out and report on the investigation of a question you originate that relates to the effect of one of the factors affecting photosynthesis/ respiration in a specific plant species. In the effect of light intensity on the rate of photosynthesis experiment, i will use a ruler to measure the distance of the lamp from the jar i will count the number of bubbles produced by marking dots on the paper as the bubbles are produced.
