Final answer:
The dominant tissue that composes most of the wood of a tree is the lignified xylem, which provides structural support and enables water transport.
Step-by-step explanation:
The dominant type of tissue that makes up most of the wood of a tree is xylem. Xylem is a complex tissue that is structurally strong and rigid, providing support to plants and allowing them to achieve impressive heights. This tissue consists of conducting cells known as tracheids, which are lignified, meaning they incorporate the compound lignin into their walls. Lignin imparts water impermeability and mechanical strength to the xylem cells, enabling them to withstand the extreme tensions required to transport water to the tops of tall trees. Such features contribute to the functions of wood, giving it durability and beauty.
The dominant type of tissue that makes up most of the wood of a tree is xylem. Xylem is a type of vascular tissue that conducts water and provides structural support to the plant. It is composed of tracheids, which have thick cell walls and large hollow centers, and parenchyma cells, which provide support and fill in the spaces between the tracheids.
