Reproduction, Morphogenesis, Nuclear Processes, and Sexuality

  • Ralph Wichterman


Binary fission—the common type of reproduction in paramecia that enables them to increase in number—is a distinctly asexual process in which one fully grown specimen divides into two daughters without leaving a parental corpse (Figure 7.1). Although binary fission is occasionally referred to as a simple, direct process, profound morphological and physiological changes occur. During the process, a complicated sequence of events takes place in organelle development in a precise, orderly manner.
