Why Does Ozone Slow Down Photosynthesis?

Published in Ozone & Photosynthesis 1 min read

Ozone slows down photosynthesis because compounds resulting from ozone oxidation interfere with energy production in plant cells. This ultimately reduces plant growth.

Here's a more detailed breakdown:

  • Ozone (O3) is a highly reactive gas.
  • When plants are exposed to ozone, it causes oxidation within their cells.
  • Oxidation products resulting from this process interfere with the function of the mitochondria, the cell's powerhouses, disrupting energy production.
  • Reduced energy production impairs the photosynthesis process, leading to slower plant growth. As stated in the provided reference: "Photosynthesis slows, resulting in slower plant growth. Compounds resulting from oxidation by ozone interfere with the cell's energy production in the mitochondria."

In summary, ozone's effect on photosynthesis is not a direct blocking of the process itself. Instead, it damages the cell's energy production, which is vital for photosynthesis to occur efficiently.
