What role does the soil play in providing raw materials for plant growth, and which plant organ is primarily involved in absorbing substances from the soil?

Soil serves as a rich source of raw materials essential for plant growth, providing nutrients like nitrogen, phosphorus, and minerals. The primary organ involved in absorbing these substances from the soil is the plant’s roots. The roots are equipped with specialized structures like root hairs and root tips that actively absorb water and minerals from the soil. This process, known as root absorption, allows plants to uptake the necessary nutrients required for various metabolic processes, growth, and overall development. The efficient absorption of soil nutrients by roots is crucial for sustaining plant health and productivity.
