In a investigation of the mitotic cell cycle, a student prepared stained sections from an onion, Allium cepa, root tip and viewed them with a light microscope. Using the microscope at high power, the student produced drawings of six cells, A to F, as shown in Fig. 6.1.
(a(i))[1]
Complete Table 6.1 to show the order of the stages in the mitotic cell cycle, using the letters A to F as shown in Fig. 6.1.
(a(ii))[4]
Table 6.2 presents several events that take place during the mitotic cell cycle in Allium cepa. Complete Table 6.2 by naming the stage of the cell cycle at which each event happens.
(b)[3]
Explain the role of mitosis in the immune response.
