Light microscopy images of xylem of a pine in close up views. The bordered piths connect the tracheids (vessels) and can act as valves to close the connections in case of pressure differences between two neighbouring vessel elements. These pressure differences can occur in case of leakage or blockage in one of the vessels. |
