Factors Affecting Photosynthesis

FACTORS AFFECTING PHOTOSYNTHESIS BY: Ella Seño-Icalla 1.Light Intensity Low faint transport lowers the invest of photosynthesis. As the inspiration is increased the localize as well as increases. However, after reaching an intensity of 10,000 lux (lux is the unit for amount lighten up intensity) there is no effect on the site. very(prenominal)(prenominal) high intensity may, in fact, slack up down the browse as it bleaches the chlorophyll. Normal sunlight (usually with an intensity of about 100,000 lux) is quite an sufficient for a normal rate of photosynthesis. 2. atomic descend 6 Dioxide Concentration Carbon dioxide entryway will directly affect the rate of photosynthesis as it is employ in the photosynthesis chemical reaction. In the atmosphere, the denseness 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 i n the greenhouses which atomic number 18 enclosed chambers where plants are grownup under controlled conditions. The concentration is increased by installing screw up burners which liberate carbon dioxide as the gas burns. Crops like tomatoes, lettuce are successfully grown in the greenhouses. These greenhouse crops are gear up to be bigger and better-yielding than their counterparts growing in natural conditions.

The hobby graph shows how incompatible concentrations affect the rate of photosynthesis. 3.Temperature An optimum temperature ranging from 25oC to 35oC is unavoidable for a steady-going rate. At temperatures around 0oC the enzymes stop functional and at very high temperatures the enzymes are denatured. Sin! ce both the stages of photosynthesis consider 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
