Solution
The correct option is C Transfusion tissue
In conifers and gymnosperms, the vascular supply in leaves is associated with transfusion tissue. It is a specialized tissue of parenchyma cells intermixed with short tracheid like cells, the walls of which contain circular bordered pits. The vascular bundle and transfusion tissue are enclosed by endodermis.
In Pinus, the transfusion tissue completely surrounds the vascular bundles. It helps in lateral conduction of mineral water and compensates the absence of lateral veins.
Thus, the correct answer is option C.
