The growth of the cell wall to Schizosaccharomyces pombe was studied by fluorescent microscopy and time-lapse microcinematography. The growth of individual cells was found to be bipolar and sharply asymmetrical. The two poles had different sequence of growth which depended on the functionation of the cell cycle. Findings concerning the growth of the poles were used for investigating the topography of the surface of zygotes. The formation of conjugation protuberances was not related to a certain pole and did not depend on its growth state. Some aspects of the cell cycle dependence of the cell wall growth and conjugation in Schizosaccharomyces pombe are discussed.
