| It is likely that lignified cells that lack membranes and protoplasm also lack sensitivity. |
| Following counter-staining with aniline blue, berberine hemisulfate stains lignified walls bright yellow, Casparian bands intense yellow-white and suberin blue white or blue. |
| The structural reinforcement of the sclerenchymatous tegmen and lignified endotesta also appears to be responsible for the unrolling of the recurved margins during imbibition. |
| Second, tracheary elements provide a water-conducting system and a support system as a result of their rigid lignified cell walls. |
| The secondary parenchyma produced by the successive cambia is not lignified and serves as a starch storage tissue. |
| The compression wood tracheids are so heavily lignified that the wood appears visibly reddish to the naked eye. |
