A study of chloroplast structure in 3 Megaceros species and 3 Dendroceros species (Anthocerotae) indigenous to New Zealand

Abstract

Investigation of the chloroplast in three species of Megaceros by light microscopy and transmission electron microscopy showed random distribution of starch and absence of a pyrenoid. Of three Dendroceros species similarly investigated, one resembled the Megaceros species, the second had a deeply convoluted and widely channelled pyrenoid with oil as the reserve material, the third showed a range of forms from one with a widely channelled, convoluted pyrenoid surrounded by a starch envelope through intermediate types to one in which the pyrenoid had extremely narrow channels and no starch envelope. © 1986 Taylor & Francis Group, LLC.
