Cell structure: outline question

Outline5 marksChallenge

A student states: 'Prokaryotic cells and eukaryotic cells are similar in that both have a cell surface membrane, 80S ribosomes, and a nucleus.' Outline the inaccuracies in this statement by comparing the three features mentioned. Do not include features not mentioned in the statement.

How this question is marked

5 marks, so the mark scheme is looking for about 5 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.
