Which consequence results when a tall tree's root surface experiences local damage impacting osmotic balance?

💡 Explanation

Restricted water root pressure causes decline in xylem water potential initiating stomatal closure. This decrease limits CO2 uptake required for photosynthesis because decreased osmotic pressure impairs water ascent, therefore carbon assimilation suffers rather than reversing flow or enhancing absorption.
