Brit.

/ˈplazməsɒl/, U.S.

/ˈplæzməˌsɔl/,

/ˈplæzməˌsɑl/

Origin: Formed within English, by compounding. Etymons: plasma n., sol n.⁶

Etymology: < plasma n. + sol n.⁶ Compare plasmagel n., plasmalemma n.

Biology.

Cytoplasm in the form of a sol, such as forms the relatively fluid central regions of amoeboid cells. Cf. plasmagel n.

1923 S. O. Mast in Proc. National Acad. Sci. U.S.A. 9 258 By careful observations on Amoeba proteus in motion the following structures can clearly be differentiated: (1) A central elongated fluid portion; (2) A solid layer surrounding the fluid portion; (3) A very thin elastic surface layer or membrane. The first I shall designate the plasmasol, the second the plasmagel and the third the plasmalemma.

1951 New Biol. 10 17 When this plasmasol reaches the tip of the pseudopodium we can imagine it gelating to form new pseudopodial wall.

1970 E. J. Ambrose & D. M. Easty Cell Biol. xi. 360 The relative viscosity of the plasma sol is quite low, being about two to ten times greater than that of water.

1987 M. S. Laverack & J. Dando Lect. Notes Invertebr. Zool. (ed. 3) ii. 20/2 In Amoeba proteus the ectoplasm forms an outer semi-rigid tube of ‘plasmagel’ enclosing an inner more fluid zone of endoplasm, the ‘plasmasol’.
