The callus consists largely of parenchyma with raphides and is supplied by eight to ten collateral bundles. |
In the vascular tissue of woody species, parenchyma cells include those in phloem, and the ray cells and axial parenchyma cells in xylem. |
There are large intercellular spaces between the irregular cells, and the parenchyma looks like aerenchyma. |
Types of paratracheal parenchyma are scanty paratracheal, vasicentric, aliform, confluent, and unilateral paratracheal. |
Droplets of extractives only appeared in the inner ring of sapwood in some cells of the ray parenchyma as small refringent bodies. |
The parenchyma in this species is much less visible than in Afara but otherwise they are very similar in structure. |
