Which consequence results when excessive manganese accumulates in plant tissues?

💡 Explanation

Excess manganese catalyses the production of reactive oxygen species, disrupting cellular membranes via lipid peroxidation. Increased transpiration rates intensify this localized toxicity because high fluxes exacerbate accumulation, therefore causing plasmolysis rather than changes to xylem diameter or ATP synthesis.
