In which kind of xylem parenchyma the parenchyma cells occur singly among the fibres and tracheids?

Diffuse apotracheal type of xylem parenchyma is the type in which the parenchyma cells occur singly or are scattered among the fibres and tracheids.
In this arrangement, the parenchyma cells are not associated with the vessels but are distributed independently throughout the xylem tissue.
This type helps in storage and lateral conduction of food materials within the wood.
Therefore, in the diffuse apotracheal type, the parenchyma cells appear isolated and irregularly dispersed among other xylem elements.
