1.	In which of the following forms is iron absorbed by plantsA. Free elementB. FerrousC. FerricD. Both ferric acid and ferrous
Answer» Correct Answer - C According to NCERT , 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 oxidised from `Fe^(2+)` to `Fe^(3+)` during electron transfer . It activates catalase enzyme . It is essential for the formation of chlorophyll.
