The student follows the typical layout of the work, although they do not follow the typical presentation of the work. The appropriate technical terms were used but the student needs to show a proper understanding of such terms by either defining them in a glossary or explaining them in the body of the work. This shows the lack of proof reading at the basic level as the word processor should pick this up automatically. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. Such questions should not occur if a piece of work answers the question fully. Transmission electron microscope is a microscope used to form an image of a specimen by transmitting a beam of electrons through it.The specimen is most often an ultrathin section less than 100nm thick or a suspension on a grid. What is considered a major disadvantage of the electron microscopes Electron microscopes can not view live cells because the method of preparation is lethal. To improve, they need to go back and explain why - re-reading over their work they will find that there were many areas where the question of "why?" or "and?" arose. The development of electron microscopes has further opened our window on the cell and its organelles. Their judgements, however, were suitable and the relevant evidence was used to support it even if it was not supported by detailed evidence. They do not explore deeply enough into the reasons behind how the microscopes work by explaining it using fundamental physics that they have learned from the syllabus.

The student's analysis is poor for A level. I feel light blue is not the best colour to use for a piece of work like this. Their response is very clearly written but not necessarily clearly presented. Why is the microscope limited in the way that it is? How does it work on a fundamental level? I think such questions are key to answering the question fully and appropriately for this level.

The student simply tends to state the advantages and disadvantages and for A level, I believe they should have explored deeper into the reasons behind it. The comparison of advantages and disadvantages is done very well but the level of detail is lacking.
