sejtfalú

Sejtfalú is a Hungarian adjective used in biology to describe cells or organisms that possess a cell wall. The term is formed from sejtfal (cell wall) and the suffix -ú, which yields the sense of “having a cell wall.” In Hungarian scientific literature, sejtfalú distinguishes cell-wall-bearing organisms from those whose cells lack a rigid external wall, such as many animal cells.

In biological usage, sejtfalú applies to a broad range of life forms. In eukaryotes, cell walls occur in plants, fungi, and many algae. In prokaryotes, most bacteria and archaea have cell walls, though some bacteria (for example, Mycoplasma) lack one. The chemical composition of cell walls varies across groups: plants typically have cellulose-based walls, fungi have chitinous walls, bacteria commonly possess peptidoglycan, and some archaea have pseudopeptidoglycan or other materials.

Usage and scope: The term sejtfalú is largely confined to Hungarian-language texts. In English, the concept would typically be described as “cell-wall-bearing” or “cell-wall-containing.” Related terms include sejtfal (cell wall) and sejt (cell).
