What is the importance of iron in plants?
✓
Answer
Iron is an important constituent of proteins involved in the transfer of electrons like ferredoxin and cytochromes. It is reversibly oxidised from $\mathrm{Fe}^{2+}$ to $\mathrm{Fe}^{3+}$ during electron transfer. It activates catalase enzyme, and is essential for the formation of chlorophyll.
