Which consequence results when increased atmospheric ozone damages guard cell membranes surrounding stomata in plant leaves?

💡 Explanation

When ozone damages guard cell membranes, disrupting ion channel function that controls turgor pressure regulating stomatal aperature control, leading to unregulated water loss via transpiration. Therefore transpiration rate increases, rather than enhanced pigment synthesis, nutrient uptake, or pathogen resistance, which rely on different cellular mechanisms.
