Within the framework of the Zhu Liang Catastrophe-Crossing Recursor Paradigm, this paper integrates two major propositions: “quantum entanglement is quantum cell” and “quantum cell and biological cell are essentially isomorphic, differing only in recursive dimension.” It systematically elaborates a unified picture from microscopic quantum entanglement to macroscopic causal cells. We prove that the universe is a multi-level self-similar recursor network, whose basic units—\textbf{causal cells}—manifest in different forms at different recursive dimensions: at the quantum dimension as entangled states (quantum cells), at the biological dimension as membrane-bound cells (biological cells), at the social dimension as civilizational units, and at the cosmic dimension as galactic structures. All causal cells obey the same recursor axioms A1–A4 and Catastrophe-Crossing Axiom A5, and their essence is the unity of causality and self-consistency. This paper integrates the latest advances in quantum biology, cutting-edge conceptions of causal cell biology, and philosophical insights from Western response-dependence theory, unifying quantum mechanics, biology, sociology, and cosmology under the Zhu Liang Catastrophe-Crossing Recursor Paradigm, revealing the profound nature of the universe as a \textbf{giant living organism}.
