Solution

The correct option is A Heart wood
  • Heartwood of most of the woody trees fails to conduct sap due to the obstruction by tyloses.
  • These are found in secondary xylem. These are outgrowths on xylem vessels of secondary heartwood.
  • When the plant is stressed by drought or infection, tyloses will fall from the sides of the cells and dam up the vascular tissue to prevent further damage to the plant.
  • These aid in the process of making sapwood into heartwood in some hardwood trees, especially in trees with larger vessels.
Thus, the correct answer is option B.
