Background

Duckweed also know as Lemna by her genus is a small plant, that is mostly found in sub-polar and tropics regions in ditches, ponds, lakes and slow flow-flowing rivers. Duckweed have the main function of remove waste of water, however the main problem is that grows fast (Moss et al.2012).

Research Question

Is the use of different concentrations of phosphates will affect the duckweed?

Hypothesis

The more phosphate use the more the plant will be affected.

Aim

To analyse the amount of phosphates that will affect the plant duckweed.

Method

• Separate 11 different cups and number them from 0 to 11. • Then in all cups add ml of water. • Add 15 duckweed on each cup. • In cup 0 start with 0% of phosphate, cup 1

On my experiment i will use phosphate another fertiliser, therefore compare my results with his results to see if the two fertiliser might have the same effects.

Phosphate are esters or salts of phosphoric acid.Phosphorus is an essential nutrient for life is fundamental for the growth and metabolic retains of all plants (Wood et al, no date). Using this knowledge of phosphate is clearly that phosphates are related to the plants,therefore is a good fertiliser to test and see if has a real effect or not on duckweed. The experiment is being done to see if the fertiliser on water as effect on the duckweed that is use as an control most of the time, a control of environment , therefore is any lake, ponds, rivers as being effect biologist can clearly see if something is happening to that specific space and see what around that space is causing the problem, therefore ifs the duckweed is being affect the biologist cannot clearly see what is something is happening or not, therefore preserving the plant can help on preventing more damage to the environment.

The most important aspects on the experiments done by other is:

The effects of fertiliser on water and plants.
What kind of fertiliser use on the
