← ScienceWhich process is inhibited when high concentrations of chloride ions surround a plant root?
A)Osmotic water uptake by roots
B)Nutrient uptake via ion transporters✓
C)Stomatal conductance in leaves
D)Photosynthesis within chloroplasts
💡 Explanation
When high chloride concentrations occur, competitive inhibition of essential nutrient uptake occurs because chloride ions have a similar charge density competing for binding to transport proteins in the root membrane. Therefore nutrient uptake is suppressed, rather than osmosis, conductance or photosynthesis, which depend on different processes.
