There are a lot of important elements needed for plants to grow – just as there are lots needed for humans to grow too.
One of the most important is oxygen, which plants need to respire – the process of using sugars to get energy.
Another is carbon, which plants take up as carbon dioxide. They convert carbon dioxide and water (H2O, so also need hydrogen!) to sugars, which they feed into reputation.
The next most important is nitrogen. Nitrogen forms the basis for proteins and DNA – so I’d say that’s pretty important. Most plants take up nitrogen as nitrate in the soil, either provided from fertilisers or produced by bacteria. Sometimes these bacteria live inside the roots as factories for nitrates – this is what I research.
The other elements provided from fertiliser are phosphorus and potassium which are also very important in basic building blocks like DNA.
There are lot of other important elements needed to – like sodium to help regulate channels for water, and magnesium to help make chlorophyll work.
So listing those you have: oxygen, carbon, hydrogen, nitrogen, phosphorus, potassium, sodium and magnesium. And there are plenty others needed to help different proteins work or build other structures in the cell.
Plants need a few elements to stay alive. These are:
Carbon
Oxygen
Hydrogen
They can get oxygen and hydrogen from water, and carbon from carbon dioxide in the air.
They also need a number of important nutrients and minerals to stay alive. Two of the most important are nitrogen and magnesium. These are usually present in good soil.
