内容記述タイプ Abstract
内容記述 The unspecified macrophyte Valonia sp. ined from Bicol Region, the Philippines portrays two distinct types of cell divisions. Higher light intensity induced lenticular cells, whereas lower light intensity produced rhizoid cells, which varied in time and structure. These initiated at stage I where chloroplasts assembledroughly at the indefinite surface of a cell. Microtubules (MTs) at the rotoplasmic assembly appeared to curve and overlap to each other. At stage II a disc-shaped assembly of protoplasm was transformedwhere radial MT arrays extended from the periphery to the central area of the protoplasmic assembly. In stage III the aggregation of protoplasm stopped, and the average diameter of lenticular cells was ca. 1 mm whereas rhizoid cells were ca. 0.1 mm in diameter. Short but dense cortical MTs were arranged randomly all over the protoplasmic aggregations, followed by the depolymerization of MTs. In stage IV septumwalls formed to divide lenticular cells or rhizoid cells from the mother cells. Densely crammed MTs were evenly dispersed all over lenticlular and rhizoid cells. Then in stage V juvenile cells started to puff out in lenticular cells and likewise elongated for rhizoid cells. New parallel arrays of MTs were formed from the base towards the apex portion of these new cells. Furthermore, the maximum attainable height measured about 2 mm in lenticular cells, while it was about 1.4 mm for rhizoid cells. Lenticular and rhizoid cellstended to develop near the zones of both ends of mother cells.
