How Does Light Intensity Affect Photosynthesis

Word equation for photosynthesis.

How does light intensity affect photosynthesis. The effect of light intensity on photosynthesis can be investigated in water plants. At low light intensities if the light intensity is increased the rate of photosynthesis increases. Word equation for photosynthesis. 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 light intensity range for most plants falls between 1 200 and 2 000 lumens measurement of light intensity. The number of light photons hitting the chlorophyll pigments increase as the light intensity rises. Light intenstity is a factor which can limit the rate of photosynthesis. In this experiment i will investigate the affect in which the light intensity will have on a plants photosynthesis process.

My aim is to determine the effect of light intensity on the rate of photosynthesis. This in turn increases the rate of photosynthesis. The whole process is so effective that in optimum conditions 90 percent of light. 2 2 chlorophyll 12 6 2.

6co 6h o c h o 6o. The plants will release bubbles of oxygen a product. Green plants and algae use light energy to make glucose and oxygen from carbon dioxide and water. Temperature carbon dioxide concentration and light intensity can affect the rate of photosynthesis.

Use cabomba or elodea which are sold in aquarium shops. 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. Light energy absorbed by chlorophyll is converted to atp and h. This will be done by measuring the bubbles of oxygen and having a bulb for the light intensity variable.

At very low light levels the plant will be respiring only not photosynthesising. Light is an important factor in photosynthesis how does a decreased light intensity impact photosynthetic rate of elodea is an important contemporary ecological question to be considered.
