If you are given a tall pea plant, how would you find out its genotype? Explain.

(i) The deficiency of any element can cause multiple symptoms. (ii) Same symptoms may be caused by the deficiency of one or several different elements. (iii) The concentration of the essential element below which plant growth is retarded is termed as critical concentration. Chlorosis is the loss of chlorophyll due to deficiency of N, K, Mg, Fe, S, Mn, Zn Mo. Different plants respond differently to the deficiency of the same element. How many of the above statement are correct?

A plant is showing symptoms like chlorosis of younger or older leaves, production of sterile flowers and grey spots. It may be due to the deficiency of
