Factors Affecting Photosynthesis

FACTORS AFFECTING PHOTOSYNTHESIS BY: Ella Seño-Icalla 1.Light Intensity Low dispirit transport lowers the invest of photosynthesis. As the brashness is increased the drift as well as increases. However, after reaching an posture of 10,000 lux (lux is the unit for amount legerity intensity) there is no effect on the tramp. very(prenominal)(prenominal) high intensity may, in fact, indisposed down the cast as it bleaches the chlorophyl. Normal sunlight (usually with an intensity of about 100,000 lux) is quite an sufficient for a normal rate of photosynthesis. 2. atomic add together 6 Dioxide Concentration Carbon dioxide submersion will directly affect the rate of photosynthesis as it is use in the photosynthesis chemical reaction. In the atmosphere, the tightness of atomic number 6 dioxide ranges from .03 to .04 %. However, it is embed that 0.1% of carbon dioxide in the atmosphere increases the rate of photosynthesis significantly. This is achieved in t he greenhouses which atomic number 18 enclosed chambers where plants are adult under controlled conditions. The concentration is increased by installing burn out burners which liberate carbon dioxide as the gas burns. Crops like tomatoes, lettuce are successfully grown in the greenhouses. These greenhouse crops are embed to be bigger and better-yielding than their counterparts growing in natural conditions.

The followers graph shows how incompatible concentrations affect the rate of photosynthesis. 3.Temperature An optimum temperature ranging from 25oC to 35oC is infallible for a steady-going rate. At temperatures around 0oC the enzymes stop work and at very high temperatu res the enzymes are denatured. Since both th! e stages of photosynthesis crave enzyme activity, the temperature has an affect on the rate of photosynthesis. 4. Chlorophyll Concentration The concentration of chlorophyll affects the rate of reaction as they absorb the light energy without which the reactions cannot proceed. Lack of chlorophyll or deficiency of chlorophyll results in chlorosis or yellowing of leaves. It can...If you want to get a full essay, order it on our website: OrderEssay.net
