Trees play a crucial role in producing oxygen, a process essential for life on Earth. This oxygen production primarily occurs through photosynthesis, where trees convert carbon dioxide and water into oxygen and glucose using sunlight. However, the mechanisms of oxygen transport and supply within trees are complex and involve various pathways and adaptations.
Photosynthesis as the Primary Oxygen Source:
Oxygen Transport via Transpiration Stream:
Corticular Photosynthesis:
Gas Diffusion in Wood:
Pressurized Gas Transport in Wetland Trees:
Adventitious Root Formation:
Trees produce oxygen primarily through photosynthesis, with leaves capturing sunlight to convert carbon dioxide and water into oxygen. This oxygen is then transported within the tree via the transpiration stream and diffusion through wood. Additionally, corticular photosynthesis and pressurized gas transport in certain species enhance oxygen supply, especially under challenging conditions like flooding. These mechanisms collectively ensure that trees can maintain their metabolic functions and continue to produce oxygen efficiently.
