| The tumor, which is often but not always associated with cystic lung lesions, may arise in pulmonary parenchyma, the mediastinum, and pleura. |
| The secondary parenchyma produced by the successive cambia is not lignified and serves as a starch storage tissue. |
| Droplets of extractives only appeared in the inner ring of sapwood in some cells of the ray parenchyma as small refringent bodies. |
| There are large intercellular spaces between the irregular cells, and the parenchyma looks like aerenchyma. |
| 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. |
