Which consequence results when a vascular plant's transpiration stream is severely inhibited?

💡 Explanation

Increased root pressure occurs because a blocked transpiration stream prevents water loss, increasing the water potential in roots that drives water upward. Therefore, root pressure becomes dominant, rather than a passive transpiration pull mechanism influencing movement of xylem.
