Hypodermis

Hypodermis ( Greek hypo under, under and dermis from derma: skin, dermis) in botany refers to the cell layer that lies directly under the outermost cell layer of the shoot, the epidermis or the root , the rhizodermis . During the growth of the roots, part of the apical meristem differentiates itself into the primordial cortex, which differentiates into the cortical parenchyma and the hypodermis, among other things. The hypodermis can serve either as a water storage tissue or as a strengthening tissue, in the first case the cells are thin-walled, in the second the cell walls are thickened. After the rhizodermis dies, the hypodermis becomes a new primary terminating tissue, the exodermis .
