Seeds are obovate, narrowly winged at the apex and acute at the base, pale brown, pubescent with hair-like outgrowths of the tegument cell radial walls, which give the surface a silky appearance.

However, by their capacity to carry spores of mycorrhizal fungi and mycorrhiza-helper bacteria on their tegument, soil springtails play a positive role in the establishment of plant-fungal symbioses and thus are beneficial to agriculture.

After the introduction of the viral particle, unpacking of the contents ( viral proteins in the tegument and the viral genome via some form of nucleic acid ) occurs as preparation of the next stage of viral infection : viral replication.
34.
The capsid has a diameter of ~ 110 nanometers ( nm ) is embedded in a proteinaceous matrix called the tegument, which in its turn is enclosed by a glycoprotein-containing lipid envelope with a diameter of about 200 nm.
35.
Such " collecting " of nutrient particles through an intact tegument is only possible because some " insulating " elements ( specifically, a basal lamina under the epitheloid and certain types of cell-cell junctions ) are not present in the Placozoa.

A simple diagram to show the difference between the teguments of free-living and parasitic flatworms : a . shows the syncytial epithelial tegument found in parasitic flatworms, such as " F . hepatica " . b . shows the multicellular, non-syncytial, epithelia, found in non-parasitic, free-living flatworms.
