Sejtállományts

Sejtállományts is a theoretical concept in speculative biology and theoretical cell biology. It refers to a hypothetical type of cellular structure or organization that is fundamentally different from known biological cells. The term is derived from a combination of "sejt" (Hungarian for cell) and "állomány" (Hungarian for stock or substance), suggesting a distinct cellular substance or underlying constituent.

The core idea behind sejtállományts is to explore possibilities beyond the established lipid bilayer membrane and cytoplasm-based structure of terrestrial life. Proponents suggest that alternative forms of cellular enclosure, energy acquisition, information storage, or metabolic processes could exist. These might involve novel molecular arrangements, different solvent environments, or entirely new principles of self-organization and replication.

Research into sejtállományts is primarily theoretical, often driven by astrobiology and the search for extraterrestrial life, where conditions vastly different from Earth might lead to unique biological architectures. It also serves as a thought experiment for understanding the fundamental requirements for life and the vastness of potential biological solutions. While no concrete examples of sejtállományts have been discovered or synthesized, the concept encourages broader thinking about the definition of life and the diversity of its possible forms. It is distinct from xenobiology, which focuses on known or hypothesized extraterrestrial organisms, by concentrating on the *potential* foundational structures of life itself.
