A plant requires magnesium for:
Options
- Aprotein synthesis
- Bchlorophyll synthesis
- Ccell wall development
- Dholding cells together.
Correct answer
B. chlorophyll synthesis
Step-by-step solution
A plants require magnesium for chlorophyllsynthesis All four sings bind with metalatom magnesium ( Mg ⁺⁺ ) , Which remain present at the centre of chlorophyll molecule. Nitrogen is the main component for the synthesis of protein. Cell wall is made up cellulose, hemicellulose and pectin components. Related Theory Magnesium is highly mobile in the plant and deficiency symptoms first appear on the lower leaves. Symptoms are more severe on the lower leaves because magnesium is moved to the new growth. Deficiency sympto
