tracheiddominated
Tracheid-dominated refers to a type of wood where tracheids are the predominant cell type. Tracheids are elongated, hollow, spindle-shaped cells that form the main component of xylem in coniferous trees and some primitive angiosperms. They serve dual functions: conducting water and dissolved minerals from the roots to the leaves, and providing structural support to the plant. In tracheid-dominated woods, these cells are responsible for the majority of the wood's physical properties, including its strength and water transport capacity.
The structure of tracheids is characterized by their thickened secondary cell walls and tapering ends that
Coniferous woods, such as pine, spruce, and fir, are classic examples of tracheid-dominated tissues. In contrast,
