Which of the following is not caused by deficiency of mineral?

Options

A. necrosis
B. Chlorosis
C. Etiolation
D. Shorteining of internodes

Answer

C

Explanation

The plants grown in dark are said to be
Etiolated. They lack chlorophyll and, therefore, appear yellow. Thus, it is not caused by deficiency of mineral nutrient.
Chlorosis is resulted due to the partial failure of development of chlorophyll which causes an abnormal colour to plant tissues.
Uncontrolled death of tissues/cells is called as necrosis.
Shortening of internodes is due to the deficiency of `Zn^(2+)` ions.
