plasmageln.

Brit.

/ˈplazmədʒɛl/, U.S.

/ˈplæzməˌdʒɛl/

Origin: Formed within English, by compounding. Etymons: plasma n., gel n.²

Etymology: < plasma n. + gel n.² Compare plasmalemma n., plasmasol n.

Biology.

Cytoplasm in the form of a gel, esp. surrounding the plasmasol in an amoeboid cell. Cf. plasmasol 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.

1942 G. H. Bourne Cytol. & Cell Physiol. iii. 97 Streaming in [the aquatic plant] Elodea cells is associated with gelation, and..is abolished by application of sufficient hydrostatic pressure to liquefy the cortical plasmagel.

1970 E. J. Ambrose & D. M. Easty Cell Biol. xi. 360 The plasma gel is located near the plasma membrane; it is generally free from granules and other inclusions.

1988 Science 19 Feb. 883/2 It became possible to examine the locomotion of the much smaller cells from vertebrate tissues, and the suggestion arose that they too possess a ‘superficial plasmagel’, although no layer could be discerned directly by light microscopy.
