Despite the presence of about 21% O 2 in the atmosphere, organs of plants and mammals are inevitably subject to lower O 2 tensions (pO 2) due to high O 2 demand in metabolic active cells and limited O 2 transport efficiency. In humans, for example, the pO 2 decreases from the … WebOct 27, 2024 · What Is Hypoxia In Plants. Hypoxia in plants is a condition where the plant is deprived of oxygen. This can happen when the plant is submerged in water or when the roots are compacted. When oxygen is lacking, the plant cannot produce the energy it needs to grow and function properly.
