[a. G. (formed by E. Strasburger in 1884 as a shortening of G. chloroplastid (A. F. W. Schimper 1883, in Bot. Zeitung 16 Feb. 108)): cf. chloro-1 and -plast.]
A plastid containing chlorophyll.
1887W. Hillhouse tr. Strasburger's Handbk. Pract. Bot. iv. 44 We can..distinguish the chlorophyll-bodies, colour-bodies, and colourless starch-builders as Chloroplasts, Chromoplasts, and Leucoplasts respectively. 1888Jrnl. Chem. Soc. LIV. 983 Between the fibrils [of chloroplastin] is the colourless metaxin, hardly visible in the intact chloroplastides. 1902H. Wager in Encycl. Brit. XXVII. 333/1 As the cell grows they [sc. the chromatophores] may become converted into leucoplasts (starch-formers), chloroplasts (chlorophyll-bodies), or chromoplasts (colour-bodies). 1906Cambr. Nat. Hist. I. 86 The cell [Zooxanthella] contains two chloroplastids, or plates coloured with the vegetal pigment ‘diatomin’. 1909R. J. H. Gibson Biol. vi. 43 The chloroplasts are minute ovoid bodies, occurring singly or in large numbers in the cells... Each consists of a basis of protoplasm permeated by an oily matter in which the chlorophyll, or pigment proper, is dissolved. 1938Weaver & Clements Plant Ecology (ed. 2) xiv. 381 Light influences the number and position of the chloroplasts. 1959J. Clegg Freshwater Life (ed. 2) iv. 77 The Green Algae all possess chlorophyll, contained..in special structures called chloroplasts. 1964New Scientist 20 Feb. 490 Chloroplasts, the small chlorophyll-containing organelles responsible for photosynthesis found within the cell substance..of green plants and algae. |
