Like all vascular plants, trees use two vascular tissues for transportation of water and nutrients: the xylem (also known as the wood) and the phloem (the innermost layer of the bark). The "damage" done by girdling restricts the movement of nutrients to the roots, thus the carbohydrates produced in the leaves do not go to the roots for storage. Bus Network Topology Working When all the nodes or computers and network peripherals are connected to a single bus for communication then it is referred to as bus network topology. Care must be used not to damage sapwood that may kill the tree or vine. In this condition, if E wants to send a packet to D, the packet must traverse the entire network to reach D.
