. Principles of modern biology. Biology. TELOPHASES DAUGHTER CELLS Fig. 3-4. Mitosis in a typical animal cell (egg cell of a sea urchin). Note particularly the asters, centrioles, and cleavage furrows. These structures are rarely found in plant CROSS SECTION LONGITUDINAL SECTION Fig. 3-5. Paired centrioles of a human tumor cell (Desille lymphosarcoma). Final magnification, X 160,000 (approximate). Note the pattern revealed by the cross section: nine triplet groups of tubules (or perhaps fibers) arranged in a circle. This pattern appears to be general, as indicated in electronmicrograph
