Exposed to a harsh environment constituted out of, uh, reality, the rightoplasm is easily damaged. In order to protect this delicate tissue, a graduated barrier grows up around the rightoplasm. The outermost layer, the cell lamebrane, is thin but tough: it detects environmental information, reverses its polarity, and passes the results through to the thick, sluggish matter lining its internal surfaces. This second layer, the lietoplasm, is itself completely insensitive to external information, but is highly chemically excitable when stimulated by the reversed product passed onto it by the cell lamebrane. Its hyperactive responses serve to distribute the anti-information throughout the internal structures of the rightoplasm.From the comments.
