Number of dictyosomes in a single cell of the green algaMicrasterias

  • Tetsuko Noguchi
Short Communication


The numbers of dictyosomes in cells ofM. crux-melitensis andM. pinnatifida were counted at various stages in the cell cycle. Dictyosomes synchronously doubled in number by dividing at the premitotic stage and then were separated into two groups by the septum, thus reducing the dictyosomal number to the ordinal number in each new cell. The number remained the same throughout the cell cycle until the next premitotic stage.
