An inner layer of cells in the cortex of a root and of some stems, surrounding a vascular bundle.
‘The endodermis surrounding the vascular cylinder of the corm effectively blocked outward diffusion of the solutes.’
‘There were no visible differences in the development of endodermis between the two varieties and growth conditions.’
‘On analysis of freeze-dried sections of flower stem, these cells were identified as large, elongated cells situated between the phloem of every vascular bundle and the endodermis.’
‘The chemical composition of cell walls from endodermis and hypodermis was analysed.’
‘It was shown to be localized to root endodermis and flowers.’
Origin
Early 20th century from endo-‘within’ + modern Latin dermis ‘skin’.
