CAIE A Level Biology 9700 · The mitotic cell cycle
A student observes a photomicrograph of a plant root tip cell in anaphase. With reference to the behaviour of sister chromatids, spindle fibres, and the nuclear envelope, outline the events that occur during prophase, metaphase, anaphase, and telophase of mitosis in this plant cell.
7 marks, so the mark scheme is looking for about 7 separate creditworthy points. Making the same point twice in different words earns it once.
Outline means: Give the main points briefly. Less detail than describe, but every key step has to be there. One short line per step, in order. The marks are for coverage, not depth.
