Tissue (biology) parts of the plant. The complex tissue consists of more than one type of cells which work together as a unit. Complex tissues help in the transportation of organic material, water, and minerals up and down the plants. That is why it is also known as conducting and vascular tissue. The common types of complex permanent tissue are: Xylem and phloem together form vascular bundles. Xylem consists of: Xylem serves as a chief conducting tissue of vascular plants. It is responsible for the conduction of water and mineral ions/salt. Xylem tissue is organized in a tube-like fashion along the main
Xylosandrus compactus and "Melia azedarach". It is particularly damaging in tree nurseries, killing seedlings and young saplings. A study in Uganda's shaded robusta coffee systems, tree species suppressing "X. compactus" infestation characteristically exuded copious sap regardless of any stress. Therefore, the presence or absence of copious sap exuding from trees upon injury likely differentiates "X. compactus" hosts from non-hosts. In Florida, where "X. compactus" has been introduced, the life cycle is completed in about twenty-eight days. Like other ambrosia beetles, the adult female carries a fungal symbiont, in this case "Fusarium solani". This fungus attacks the xylem tissue of the plant host,
