Ferns have well-developed vascular tissue, roots, and stems. Pits are present in lignified walls to remove a blockage caused by air. These walls are constructed of layered sheaths of cellulose microfibrils, wherein the fibers are in parallel within each layer. 2. Log in. The ground tissue of plants includes all tissues that are neither dermal nor vascular.It can be divided into three types based on the nature of the cell walls. Meaning of lignified?? These make them more rigid in comparison to the parenchyma and the collenchyma cells. i. Loss of lignification in this domain leads to an increased endodermal permeability and a loss of mineral nutrient homeostasis.
