Which outcome of extreme heat occurs within non-irrigated plant xylem?

💡 Explanation

Tensile strength decreases because high temperatures increase water molecule kinetic energy, thereby reducing hydrogen bonding and the cohesion-tension mechanism's effectiveness, rather than raising root pressure; therefore, transport fails.

• Which consequence occurs when a Batesian mimic fails?
• Which risk potentially increases under high leaf temperatures when rubisco preferentially binds oxygen?
• Which developmental outcome occurs when ecdysone receptor genes lack expression?
• Which outcome results when a freshwater teleost's osmoregulation fails?
• Which risk increases when foraging honeybees rely exclusively on outdated floral maps?
• Which outcome results when a songbird's syrinx is constrained?
