Even if cells were able to contemplate the significance of being components of a greater whole, the fact that each retains only a minuscule piece of the knowledge necessary to understand this reality means that it would be impossible to fully comprehend its intricacies. Projecting this onto human constituents of a species awareness yields the same conclusion. We can communicate over great expanses via wireless technology, transferring vast amounts of data using a minimal amount of energy. Mere watts of power allow people on Earth to interact with probes in the far reaches of our solar system. Considering the incredible potential energy harnessed within a single atom, distance is not a hindrance to biological communication beyond a microscopic level.
Proximity is relative to the time it takes energy to cross a given space.
Thought processes in your mind seem instantaneous, but are actually restricted by the speed of light, which limits known forms of energy to approximately three hundred thousand kilometres per second. Although ensuring the survival of an individual sometimes requires an almost instantaneous reaction, the perpetuation of a species does not. A species reacts via evolution, and this is accomplished generation by generation. Speed is not a factor when response intervals substantially exceed the time it would take to communicate. Being that our participation would be on a subconscious level, and each of us is the repository for mere billionths of the knowledge required to create the sum of such an awareness, comprehending it would be logically impossible.
