"WebIn eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

WebResting B and T lymphocytes (those in the G 0 phase of the cell cycle) are classed histologically as “small lymphocytes” (refer to Fig. 3-1). Morphologically, small lymphocytes are round cells with a large nucleus surrounded by a narrow rim of cytoplasm. Comparatively few intracellular organelles are contained in the cytoplasmic rim. WebDifferentiation from visibly undifferentiated precursor cells occurs during embryonic development, during metamorphosis of larval forms, and following the separation of parts in asexual reproduction. It also takes place in adult organisms during the renewal of tissues and the regeneration of missing parts. Thus, cell differentiation is an essential and …
