Cells - worked exam question

This uses an AQA exam question. I broke this question down to explain how I would go about answering it. I always say how important it is to study the information at the beginning of a question before you read any part of the question itself.
I show slide 1 then I get students to divide a page in their exercise book into 4 quarters and draw a quick sketch diagram of each cell with room below to write. Then I get them to identify the parts of each cell and also what each cell is missing.
Then we discuss what each cell is and identify the reasons for each answer. Working through the next 5 slides adding to their notes if they miss any important points.
Lastly I go through the questions themselves on the last slide.
Parts 1.1 and 1.2 will already have been identified but there may still be discussion around the reasons used.
Part 1.3 may need revision of the terms eukaryote and prokaryote before the answer can be found.
Part 1.4 uses the equation for magnification. Encourage students to use calculators to check their answers. (Calculators are allowed in science exams so why not use them as it is so easy to make silly mistakes under the pressure of exams.)
May need to revise relative sizes of millimetres and micrometres.
