mycelium → fungal infection
sapwood → - In the center of trees, the darkened, older layers of secondary xylem made up of cells that no longer transport water and are clogged with resins.
Lichen → A close association between a fungus and an alga or between a fungus and a cyanobacterium, some of which are known to be beneficial to both partners.
Definition of fungi → heterotrophic eukaryotes; digest food externally and absorb the nutrients; found everywhere (soil and water); mostly decomposers, some parasitic
root tip zones → An outgrowth of an epidermal cell on a root, which increases the root's absorptive surface area.
