Plants use a similar mechanism to move water through their stems. In a specific species of plant, the vessels are approximately 0.3 mm in diameter. Estimate how tall this species of plant can grow. Explain how the molecular structure of the vessels can be modified to increase the maximum height of the plant without changing the diameter of the vessels.
