Why Is Root Respiration Important?

Root respiration plays a crucial role in plant physiology due to its significance in energy production and the facilitation of essential metabolic functions. This process involves the combustion of glucose within root cells, which has been previously transported from the leaves through the plant’s vascular system. During this metabolic process, glucose is converted into a vital energy molecule known as adenosine triphosphate (ATP). ATP serves as the primary source of energy to drive various metabolic processes, particularly the uptake of water and nutrients from the soil. It’s important to note that oxygen is a fundamental requirement for root respiration to occur. Without a sufficient supply of oxygen, the process of respiration cannot take place, impairing the plant’s ability to sustain its vital functions. This underscores the critical role of root respiration in a plant’s overall health and growth. [Updated: September 12, 2022]

Why Can Roots Of Plants Breathe?

Why Do Plant Roots Have the Ability to Breathe?

Plant roots possess the remarkable capability to extract essential gases from the soil, enabling them to thrive and perform vital functions. This process involves the absorption of air from the tiny spaces between soil particles, facilitated by specialized structures known as root hairs. These hair-like extensions on the root’s surface come into contact with the air present in the soil particles. Specifically, oxygen in the soil particles undergoes a process called diffusion, allowing it to enter the root hairs and subsequently diffuse throughout all the cells of the root. Once inside the root cells, oxygen plays a critical role in the process of respiration, providing the necessary energy for various metabolic activities essential for the plant’s growth and survival. This ability of roots to access oxygen in the soil is fundamental for the overall health and vitality of plants.

Explain respiration in plants

Roots, the underground part of the plants, absorbs air from the air gaps/spaces found between the soil particles. Hence, absorbed oxygen through roots is utilized to liberate the energy that in the future, is used to transport salts and minerals from the soil.In respiration, root cells burn glucose that’s been transported from the leaves. Glucose is transformed into cellular energy (called adenosine triphosphate or ATP) that’s used to drive metabolic processes, mainly water and nutrient uptake. Without oxygen, respiration does not take place.A plant’s roots absorb air from the gaps between soil particles. The air in the soil particles comes into touch with the root hairs. The oxygen in soil particles diffuses into root hair and reaches all of the root’s cells, where it is used in respiration.
