The capsule wall cells remain alive, even after dehiscence, and have many cytological features in common with food-conducting cells in bryophytes including highly differentiated plasmodesmata. Whereas the highly ornamented spore exine retains water, the elaters are hydrophobic due to a coating of lipid...
The distribution of arabinogalactan—proteins and pectic polysaccharides restricted to specific wall types and stages of development provides evidence for the developmental and functional regulation of cell wall composition in bryophytes. Monosaccharide-linkage analysis of Sphagnum leaf cell walls suggests they...
