A researcher observes that water absorption by roots is significantly reduced when the plant is treated with a respiratory inhibitor. Which of the following best explains this observation?
Respiratory inhibitors directly block aquaporin function, preventing water movement.
Respiration is essential for maintaining root cell turgidity, which is directly linked to water absorption.
Active transport of ions into the root cells requires energy, creating a water potential gradient that drives water uptake.
Inhibition of respiration disrupts the cohesion-tension theory, preventing water movement through the xylem.
