Further observations on the fine structure of the haptonema in prymnesium parvum
Tóm tắt
Information has been provided for the first time on the fine structure of the tip and base of a haptonema, the organism being that already studied in a preliminary way in Manton and Leedale 1963 a. The tip structure is unexpectedly simple, with the haptonema cavity interposed between the rounded apex of the core and the external wall of the organelle. The base has been shown to be unexpectedly complex in that the number of core fibres, which alone enter the cell deeply, changes progressively from 7 at the surface to 9 at the extreme base. The possible meaning of these observations is discussed in a preliminary way.
