Many transplanted seedlings do not grow becausea)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.Correct answer is option 'C'. Can you explain this answer?

Question

Answer

Reasons why many transplanted seedlings do not grow:

- Loss of root hairs during transplantation: When seedlings are transplanted, they may experience damage to their delicate root hairs. These root hairs are responsible for absorbing water and nutrients from the soil. If a significant portion of the root hairs are lost during transplantation, the seedling may struggle to establish itself in the new soil and ultimately fail to grow.

- Impact on nutrient uptake: With the loss of root hairs, the seedling's ability to uptake essential minerals and nutrients from the soil is compromised. This can lead to stunted growth and poor overall health of the plant.

- Root system shock: Transplanting can cause stress to the root system of the seedling, disrupting its ability to take up water and nutrients effectively. This shock can hinder the growth of the plant and make it more susceptible to diseases and pests.

- Reduced stability: The loss of root hairs can also impact the stability of the seedling in the new soil. Without a strong root system, the plant may struggle to anchor itself properly, making it more vulnerable to being uprooted by wind or other environmental factors.

In conclusion, the loss of root hairs during transplantation is a critical factor that can contribute to the failure of many transplanted seedlings to grow. It is important to handle seedlings carefully during the transplanting process to minimize root damage and give them the best chance of thriving in their new environment.

Answer

Reasons why many transplanted seedlings do not grow:
- Loss of root hairs: During transplantation, the delicate root system of the seedling may suffer damage, leading to the loss of root hairs. Root hairs play a crucial role in absorbing water and nutrients from the soil. Without a sufficient number of intact root hairs, the seedling may struggle to establish itself and obtain the necessary resources for growth.
- Poor soil conditions: The new soil in which the seedling is transplanted may lack essential minerals and nutrients required for healthy growth. If the soil does not provide the necessary resources, the seedling may not be able to thrive and may eventually wither.
- Roots not adapting to new soil: When a seedling is transplanted, its roots need to adapt to the new soil conditions. If the new soil differs significantly from the soil in which the seedling initially grew, the roots may have difficulty adjusting and establishing a strong hold. This can lead to poor nutrient uptake and hinder the growth of the seedling.
- Damage to leaves: Transplantation can sometimes result in physical damage to the leaves of the seedling. Leaves are essential for photosynthesis, the process by which plants convert sunlight into energy. If the leaves are damaged or compromised, the seedling may struggle to produce enough energy to support growth.
Overall, the loss of root hairs, poor soil conditions, roots not adapting to new soil, and damage to leaves are all potential reasons why many transplanted seedlings do not grow successfully.
