UPSC Prelims 2013 question on Transplanting Seedlings Root Hairs

Many transplanted seedlings do not grow because:

  1. The new soil does not contain favourable minerals
  2. Most of the root hairs grip the new soil too hard
  3. Most of the root hairs are lost during transplantation
  4. Leaves get damaged during transplantation
Show answer

Answer: C. Most of the root hairs are lost during transplantation

During transplantation, delicate root hairs are often damaged or destroyed. Root hairs are essential for absorption of water and minerals from the soil. Loss of these root hairs reduces the plant’s ability to absorb sufficient moisture, leading to transplant shock and poor growth. Therefore, seedlings often fail to grow because most root hairs are lost during transplantation. Extra Point: Transplant shock can be minimized by watering properly and reducing root disturbance during transplantation.
