Correct Answer:
(C) Most of the root hairs are lost during transplantation
Many transplanted seedlings do not grow because most of the root hairs are lost during transplantation. The function of root hairs is to collect water and mineral nutrients present in the soil and take this solution up through the roots to the rest of the plant. These are made up of cellulose and nominal Pectin which helps it as a gelling agent with the soil. Another reason is the use of fertilizers which increases the concentrations of the soil and make it difficult for plants to absorb water. This situation causes plant cells causing the leaves turn brown.
