UPSC 2013: Many transplanted seedlings do not grow because
(a)the new soil does not contain favourable minerals
(b)most of the root hairs grip the new soil too hard
(c)most of the root hairs are lost during transplantation
(d)leaves get damaged during transplantation
Attempt This Question
Not attemptedCorrect Answer: (c) most of the root hairs are lost during transplantation
During transplantation the delicate, single-celled root hairs that absorb nearly all water and minerals are torn off; without these hairs the seedling cannot take up enough water and often wilts or dies. Mineral content of new soil or leaf damage are secondary and root hairs do not ‘grip’ new soil too hard; loss of root hairs is the primary cause.
