The photomicrograph shows plant cells in different stages of the mitotic cell cycle. Four of the cells are labelled with a number to identify them. [Figure 20.1] One of the numbered cells is within the main stage of mitosis in which the spindle begins to form. A second numbered cell is within the main stage of mitosis in which the spindle fibres shorten. Which row correctly identifies the two cells that are in these stages of mitosis?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
Astage in which spindle begins to form: 1, stage in which spindle fibres shorten: 2
Bstage in which spindle begins to form: 2, stage in which spindle fibres shorten: 1
Cstage in which spindle begins to form: 3, stage in which spindle fibres shorten: 1
Dstage in which spindle begins to form: 4, stage in which spindle fibres shorten: 2
✓ Correct answer
D: stage in which spindle begins to form: 4, stage in which spindle fibres shorten: 2
