Plants absorb iron mostly in the form of ferric (

Fe^{3 +})

ions. However, plants in acidic soil can absorb iron in ferrous

(Fe^{2 +})

as well as ferric

(Fe^{3 +})

form. It is an important constituent of proteins involved in the transfer of electrons like ferredoxin and cytochromes. It is reversibly oxidised from

Fe^{2 +}

to

Fe^{3 +}

during electron transfer. It activates catalase enzyme. It is essential for the formation of chlorophyll.
