Does light intensity affect the rate of photosynthesis in elodea plants hypothesis: yes, light intensity does affect the rate of photosynthesis too much light may. The rate of photosynthesis is affected by a number of factors including light levels, temperature, availability of water, and availability of nutrients. So even if the rate of photosynthesis per unit leaf area does not change, the growth rate due to reduction in total plant photosynthesis. Photosynthesis lab what is the effect on the rate of photosynthesis of spinach leaves when they are in an environment of different concentration of carbon dioxide.
In this lab, students test the effect of light color on the rate of photosynthesis given the equation for photosynthesis. Abstract the purpose of this experiment is to observe the factors affecting the photosynthetic rate of leaves, which is measured in two ways. Photosynthesis: photosynthesis, process by which green plants and certain other organisms transform light energy into chemical energy. The rate of photosynthesis often limits plant growth when availability of water in the soil is limited a negative whole-plant carbon balance could occur. 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.
Factors that influence the rate of photosynthesis and oxygen production in aquatic plants water color dissolved substances in the water, such as naturally-occurring. Factors affecting the rate of photosynthesis the main factors are light intensity, carbon dioxide concentration and temperature, known as limiting factors. Find out what the products of photosynthesis are and view the overall chemical reaction and equation factors that affect the rate of photosynthesis. Looking at limiting factors of photosynthesis and investigating light intensity aqa.
Three factors can limit the speed of photosynthesis - light intensity, carbon dioxide concentration and temperature if you plot the rate of photosynthesis. Photosynthesis is a process used by plants and other organisms to convert light energy the average rate of energy capture by photosynthesis globally is. A brief outline of various ways to measure the rate of photosynthesis - including measuring photosynthesis via the uptake of carbon dioxide (eg using. 1 rate of photosynthesis: limiting factors limiting factors the main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration. Did you ever wonder how scientists measure the rate of photosynthesis this video will walk you though how photosynthesis is measured, at the leaf level.
Photosynthesis is the cornerstone of physiological process and the basis of drymatter production in plants photosynthetic rate is an important parameter. Factors affecting the rate of photosynthesis the term rate always involves time, so the rate of photosynthesis can be considered to be how fast photosynthesis takes. Photosynthesis definition, the complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae. Science fair project which compares the rates of photosynthesis for various light sources which type of light will be best for photosynthesis and why. Photosynthesis occurs in chloroplasts that contain protein controls the rate of electron transfer mainly through the distance between the donor and.
