1.	Question : Select the correct statements. (i) Between temperature range 0 - 25^(@)C, rate of respiration doubles for every 10^(@)C rise in temperature. (ii) Cytochromes are iron-porphyrin compounds. (iii) Respiratory rate of wounded or injured plant parts generally decreases.
Answer» (i) and (ii) (ii) and (iii) (i) and (iii) (i),(ii) and (iii) SOLUTION :Wounding or injuring an organ of a plant increases the rate of respiration. It is probably due to the formation of GROWTH hormone, traumatic acid, which increases the MERISTEMATIC ACTIVITY, RESULTING in callus formation.
