This finally means that water and carbon dioxide produce sugar as the plants energy, then the plant releases oxygen and water stays in the roots of the plant. Method: 1. Light is one of the external factors that affect the rate of photosynthesis. Experiment to show the effect of different wavelengths of light during the process of photosynthesis: Requirements: A large ‘Ganong’s light screen’-like box in which the leaf can be inserted, glass top covered with blue, green and red colours, plant twig, stand, iodine, etc. Photosynthesis is the process by which a plant cell converts carbon dioxide (CO2) to food sugars via light energy. The number of light photons hitting the chlorophyll pigments increase as the light intensity rises. In this experiment, a Hydrilla sprigs, a beaker, test tube, funnel, water, box, and light source are needed. This in turn increases the rate of photosynthesis. The inhibitory effect of oxygen on photosynthetic Co 2 fixation in higher plants is somewhat higher at wavelengths which excite preferentially photosystem I.
MATERIALS AND METHODS. The light intensity range for most plants falls between 1,200 and 2,000 lumens (measurement of light intensity). Investigating the Effect of Light Intensity on Photosynthesis g Criteria: Pl (a), Pl (b) Background The candidate is asked to desi gn an experiment to investiate the influence of liht on photosynthesis. At the lowest CO2 concentration there was no effect on photosynthesis of the light intensity at which the plants were grown.
The formula for photosynthesis is 6H2O + 6CO2 ------ïƒ C6 H12O 6 + 6O 2.
Experiment # 5. The aim of the experiment was to determine whether different light intensities have different effects on the rate of photosynthesis of two plants, one grown in normal light conditions and one grown in shade conditions. Photosynthesis is processing light. min). Place a potted plant in darkness for about 24 hours. 4. A very small fraction of light wavelength can be trapped by the green plants and utilized in photosynthesis.
The rate of photosynthesis is directly proportional to light intensity (Kent, 2000). The candidate is given a sample of Elodea, and access to the appropriate laboratory equipment is … Study of the Effect of Monochromatic Light on Photosynthesis: The quality, intensity and duration of exposure to light are some of the principal limiting factors of photosynthetic process in green plants.
