plasson Biol.|ˈplæsən|
[a. G. plasson (Haeckel), a. Gr. πλάσσων, -ον, pres. pple. of πλάσσειν to mould, form.]
Name for the homogeneous protoplasm of hypothetical primitive organisms, not yet differentiated into nucleus and general cell-substance, or for that of non-nucleated cells or cytodes.
1879tr. Haeckel's Evol. Man I. vii. 182 The vital activities of each cell form a sum of mechanical processes, which depend radically on movements of the smallest ‘life-particles’, the molecules of the living substance. If we call this active substance the Plasson, and the molecules the Plastidules, we may say that the individual physiological character of each cell depends on the molecular movement of its plastidules. 1904McCabe tr. Haeckel's Wond. Life vii. 163 On the first view, which I hold, the plasm, or living matter, of the earliest organisms on the earth..was a homogeneous plasson or archiplasm—that is to say, a plasma-compound that was not yet differentiated into outer cytoplasm and inner caryoplasm.
Hence plaˈssonity (humorous, after paneity, etc.), the quality of being ‘plasson’.
1882Coues Biogen (1884) 33 The original arch-amœba is as much of a mystery as ever; we know not where he came from, how he got there, or in what the essence of his plassonity subsists. |
