ABSTRACT
A study was made of tissues of diploid and haploid Xenopus laevis larvae by electron microscopy. The comparison of the two types of larvae was both quantitative and qualitative. Haploid cells contain fewer similarly sized mitochondria and/or cilia (compared with the diploid), commensurate with their smaller cell size. Cellular differentiation is retarded in haploids and the degree of retardation is reflected in the retention of cellular lipid and yolk. It is suggested that the failure to differentiate adequately is an important component in the development of the haploid syndrome.
