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.’
- ‘The chemical composition of cell walls from endodermis and hypodermis was analysed.’
- ‘It was shown to be localized to root endodermis and flowers.’
- ‘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.’
Early 20th century: from endo- ‘within’ + modern Latin dermis ‘skin’.
