Topic: why is it important to study and understand nitrate uptake in plants?
June 24, 2019 / By Abbie Question:
ok i got this postgraduate assignment to do about "critically evaluating our understanding of nitrate uptake in plants and algae". Its pretty deep stuff.
In the opening paragraph i need to state why we need to understand and the purpose of it. Nitrogen obviously is important cos it is incorporated into proteins, which is needed by all living things. what else can i put in the introductory paragraph as to why we should understand nitrogen uptake by plants?

Nitrates allow life. The uptake of them allow protein synthesis of plant material, without it plants could not grow, and animals could not survive (considering that plants are the only Kingdom that can convert light energy into chemical, with the exception of a few bacteria).
Nitrates are needed to be incorporated into nucleic acids. Free ones found in the cytoplasm are needed during the replication of DNA (semi conservative model).
We need the plants to do this so we ourselves can use them for our own protein synthesis.
As nitrates cannot be 'made', you should reinforce the importance of the nitrogen cycle.
You could perhaps go deeper and talk about the use of fertilizers that contain nitrates and allow excess plant growth (eutrophication), especially in the case of leaching of the soil in farmers fields, which could allow the fertilizer to run into nearby rivers and streams, allowing mass algae growth. This in turn increased the biological oxygen demand (BOD) removing O2 from the water. More algae means more dead material, making way for detritivores and decomposers - also with a high BOD. This leaves even less O2 in the water and animals in the stream begin to die - adding to this spiral of decline.

because they are our main source of food. if there were no plants, there would be no life. plants provide us with oxygen for our bodies and remove carbon dioxide that we produce as waste from the air. they are the main source of food for animals that we need. they provide us with nitrogen so we can make our own proteins. basically, they are very important as there would be no life without plants.
does that help?
Because when surface runoff carries excess nitrogen into a water body, say a lake, there will be nutrient enrichment in the lake. Nutrient enrichment begets eutrophication. Eutrophication begets a change in water chemistry, stratification and consequently biodiversity.

Nitrates in the water supply have serious consequences for human health including affecting the ability of babies to breathe.
And excess nitrogen can kill fish and plants. Consult my article:
for additional examples of how improper use of nitrogen ruins plants and people. It tells you the correct way to feed your plants and limit your use of fertilizers.
