Hint: Macro elements are the elements that the body needs in the more amount to the body and examples are calcium, potassium, magnesium, etc, while microelements are the ones which need in trace amounts, which are manganese, zinc, etc.
Complete answer:
Macroelements:
They usually occur in plants, and can easily detectable them.
The concentration of the macro elements is usually one microgram/one gram, in a dry matter.
Macro elements generally buildup the plant body, and other protoplasmic constituents.
Some of the macro elements are easily accumulated in the cell sap and develop some osmolarity.
Turgor movements mostly occur because of the influx and efflux of the macro elements, mainly because of potassium, which is again a macro element.
Whereas macro elements do not become toxic, even when they are little excess in the body.
Examples include carbon, sodium, potassium, oxygen, etc.
Microelements:
Microelements are found very little in concentration in plants.
The concentration of microelements, include 0.1mg/gm of the dry matter.
Microelements do not play any role in plant body buildup and its functions.
As the concentration of the macro elements is found in traces, they do not have any role in osmolarity.
Microelements do not have any significant function in the plants.
Whereas the presence of little excess of the microelements is toxic to the plant body.
Examples of the microelements are copper, manganese, etc.
Note:
Soil elements are divided into three categories, mainly macro, micro and other more are meso elements, which are like sulfur, etc. For the plant to grow properly all of these elements should be in a balanced state.
