However, a bad seal can mask even superior water vapour barrier properties of materials.
Prehydration in water vapour was needed to prepare the embryoids for full imbibition.
The problem of diffusion distance appears to have affected several attempts to estimate the capacity of seeds to imbibe water vapour.
This is also the case for water vapour.
The available agents differ in their properties of permeability to water vapour and wound protection.
At little metabolic cost they would be able to scavenge the atmosphere for the little water vapour present.
We therefore speculate that a highly insulating foam of desorbed water vapour developed at the top of the sill.
The immediate source of water should be the atmospheric water vapour.
