Level Achieved: L3 Achievement P M D Resubmission? Y N Title of Access to HE Diploma: Biomedical Science Unit title: Cells Unit code: CBB508 Learner: Tutor/Assessor: Raquel BALDAN VOWLES Description of Assignment: This unit is assessed through a mixture of written tasks, questions and answers and drawings contained in one workbook. There is a word limit of 2000 words (+/- 10%) for the whole assignment. Task 1 involves composing a handout for a fellow student who missed the lecture on the relationship between structure and function of cell organelles and cellular specialisation. [AC1.1, AC1.2] Task 2 involves answering a series of short questions on the plasma membrane, movement of molecules across the membrane and levels of organisation in body systems. [AC2.1, AC2.2, AC4.1] Task 3 involves completing a table to compare the similarities and differences between mitosis and meiosis and answering a structured question relating to the role of these processes in adults. [AC3.1] Task 4 involves writing an outline for a magazine article on how medical science uses stems cells in the development of treatments and/or research [AC4.2] See attached task instruction sheets for details. ● Where you use information or facts from a source such as a textbook or website, ensure that your work is referenced in the text and you include a reference list.

This is what you must be able to demonstrate that you can do in your assignment in order to achieve the unit. The learner will: The learner can: 1. Understand the structure of the eukaryotic cell and the functions of the different components. 1.1. Explain how the structure of the main organelles is related to their function. 1.2. Explain how cells are specialised for particular functions. 2. Understand the structure of the plasma membrane and its role in transport of substances and cell communication. 2.1. Explain the roles of the components of the plasma membrane. 2.2. Compare and contrast the four methods of transport of molecules across a plasma membrane. 3. Understand the processes of cell division. 3.1. Compare and contrast meiosis and mitosis. 4. Understand the nature of multi-cellular organisms. 4.1. Differentiate between the various levels of organisation in two named body systems. 4.2. Explain the potential of stem cells in research and/or medicine. Level 3 units only: Learners achieve a Pass if they meet all Level 3 Assessment Criteria for a unit. You will achieve a Merit or Distinction by meeting the following Grade Descriptors. Your tutor will give you feedback for all three grades. Grade Descriptor Merit Distinction GD1: Understanding of the subject The student, student’s work or performance demonstrates a very good grasp of the relevant knowledge base. The student, student’s work or performance demonstrates an excellent grasp of the relevant knowledge base. GD2: Application of Knowledge The student, students’ work or performance makes use of relevant facts and concepts with very good levels of insight and The student, students’ work or performance makes use of relevant facts and concepts with excellent levels of insight and analysis 3 © OCN London 2021 analysis GD7: Quality The student, student’s work or performance taken as a whole, demonstrates a very good response to the demands of the brief/assignment. The student, student’s work or performance taken as a whole, demonstrates an excellent response to the demands of the brief/assignment. Grade Guidance: Learners must carefully read the guidance below which is linked to the components above MERIT: GD1: Understanding of the subject You will demonstrate a sound understanding of cell processes. This will be done to a Merit level by: ● Covering the main points required by each of the questions using appropriate scientific terminology and examples in your explanations. At Merit level, you may make some minor errors such as in the form of a term used (e.g. synthesise rather than synthesis) but your meaning will be clear. ● Where you are supporting your explanations with diagrams or images, these will either be hand- drawn or carefully selected to ensure that they generally display information that is relevant to the point you are making. Diagrams will be correctly labelled – at a Merit level there may be minor errors or irrelevant information in some of your diagrams, but the majority will be relevant and accurate. ● You will correctly identify most of the information not given to you in the task (e.g. organelles in task 1, A to E in task 2). GD2: Application of Knowledge ● Across all the tasks, you will not just copy facts from your wider reading but will generally relate the information that you have found to the question that you are asked to answer. ● In tasks 1 and 2, where required, you will generally make insightful links between structure and function – this means you will provide a clear explanation of the structure and explain how this structure helps the component to perform its function. You will identify most of the key organelles and structures in your chosen specialised cell and explain how they contribute to the function of the specialised cell. ● Your answer for Task 4 will demonstrate a very good level of insight or analysis into the use of stem cells in research or medicine. To do this to a ‘very good’ level, you will include either scientific or ethical considerations. You will have used your insight to focus on a consideration (or considerations) that are particularly relevant to the example of the use of stem cells you have chosen. You will show some analysis by explain why that consideration is scientifically or ethically important. GD7: Quality ● Most of your writing will be fluent and logical. You will achieve this by generally ordering your sentences correctly and writing in a manner that is generally accurate in terms of spelling, punctuation and grammar. Your writing will generally have an academic tone. ● Where you have used information from your wider reading, this will be cited in your work. At a Merit level, there may be some minor irregularities in terms of following the Harvard style when citing in- text or in the reference list. ● You will use a range of resources to find information. ● Your work will be within the overall word limit of 2000 words (+/-10%). ● Images and drawings will be clearly labelled and be applicable to the assignment. 4 © OCN London 2021 ● Tasks will be clearly labelled and, overall, the work will be generally well-organised. DISTINCTION: GD1: Understanding of the subject You will demonstrate a detailed and deep understanding of cell processes. This will be done to a Distinction level by: ● Covering all of the points required by the tasks, consistently using scientific terminology in your explanations in the correct form and context and by using relevant examples. ● Where diagrams and images are used, these will consistently display the information that is relevant to your response. In order to have relevant diagrams, it is likely that you will have produced hand- drawn diagrams so that they are focused on what is required by the task. Diagrams will be labelled accurately and clearly. ● You will correctly identify all of the information not given to you in the task (e.g. organelles in task 1, A to E in task 2). ● You will offer some relevant examples and explanations that further demonstrate understanding for example, in task 2 named substances moving across the plasma membrane in specific cells, or in task 3 why identified differences in mitosis and meiosis exist. GD2: Application of Knowledge ● You will consistently relate the facts that you have found from your wider reading to the questions you are asked to answer. Your wider reading will be focused on reputable, accurately cited academic textbooks and sources. ● In tasks 1 and 2, where required, you will make consistently insightful links between structure and function. Your response will take an analytical approach to explaining how the structure of the component (and not another structure) allows it to perform its function – to do this analytically then you might compare the structural forms and functions of different components to explain why they are different, or make reference to limiting factors and how these impact on structure and function (e.g. size, where a component is located). You will identify all of the key organelles and structures in your chosen specialised cell and explain how they contribute to the function of the specialised cell. ● In task 3 Q2, your response will consistently be relevant to a healthy biological male
