Light wavelength effect on the photosynthetic rate of elodea.

Introduction:

The rate of photosynthesis varies greatly with changes in wavelengths of swinging. Lights colour is determined by its wavelength of roost, and thus it is possible to devise an test to determine which wavelengths of light are closely productive for photosynthesis than others.

In this experiment I exercise a plant called Elodea (pond weed). Elodea is native to northwesterly America and it is also widely used as marine museum vegetation. The basic structure of these plants are whirls of leaves around a bag that form a chain of long segments connected to looks homogeneous pipe cleaners with usually a diameter of most half an inch or so, depending on the species of elodea plants. loose sediments and water rich in nutrients favour the wrickth of American waterweed in nutrient-rich lakes. I use this plant because it provide grow in a wide range of conditions, from very modify to deep water, and in many sediment types. It can up to now continue to grow unrooted, as floating fragments.

The purpose of this experiment is to see under what conditions the elodea plants grow and photosynthesize the best. To accomplish this, the plants were subjected t different light colours (Blue, Green, reddish and purple). This test will allow us to see which wavelength (colour) will allow the most light the elodea plant needs to flourish.



Besides the light factor I also decided to put a 100 watt lamp above each plant so I get a high light military strength to speed up the rate of photosynthesis.

Aim:

The purpose of this experiment is to mark out under what wavelength (different colour of light) the elodea plants are fit to grow and photosynthesise the best. This experiment was consisted of 4 different colours of light, Blue, Green, Red and Purple.

Hypothesis:

I predict that the plant...
