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 e
ors 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 co
ectly labelled – at a Merit level there may be minor
e
ors or i
elevant information in some of your diagrams, but the majority will be relevant and
accurate.
● You will co
ectly 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 co
ectly 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 i
egularities 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 co
ect 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 co
ectly 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 mem
ane 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

Q1.
a. The organelle responsible for production of energy
Mitochondria are the cell organelles responsible for producing energy for the cell in the form of ATP’s. Mitochondria are mem
ane bound organelles. The peculiar feature of mitochondria which make responsible for producing energy is that they are mem
ane bound with two different mem
anes which is unusual for inter cellular organelles. The structure of these mem
anes facilitates production of chemical energy stored inside the cell in the form of ATP’s. This energy is needed by the cell to perform different biochemical reactions. Mitochondria have their own chromosome. Different cells have different number of mitochondria depending on their requirement of energy for various functions.
. The organelle involved in protein synthesis
Ribosomes are the cellular organelles responsible for protein synthesis. Ribosomes are generally large complexes of RNA (ribonucleic acid) and proteins synthesized in nucleolus of nucleus. The protein synthesis occurs when ribosomes receive order from nucleus wherein transcription of DNA to mRNA takes place. This mRNA then travels to ribosomes where translation process occurs and the sequences of nitrogenous bases in mRNA is translated into specific order of amino acids to from a large chain protein molecule. Ribosome structure plays a important role in protein synthesis which is made up of two subunits, the big and small subunit which comprises of ribosomal RNA molecules and ribosomal proteins. The mRNA bins to the smaller subunit and the larger subunit are the place where amino acids are incorporated.
c. The organelle which controls the activities of the other organelles in the cell
Nucleus is the cell organelle found in eukaryotes, which controls the activities of all other cell organelles and therefore is also known as the command centre. IT do so by storing genetic material inside in the form DNA. The nucleus controls different activities of cell including growth and metabolism. The nucleolus is subpart of nucleus which has RNA that serves as the template for protein synthesis. The structure of nucleus is spherical shaped bound with nuclear mem
ane. Inside the nucleoplasm is found nucleolus and chromosomes. It is responsible for coordination of genes and gene expression.
Q2.
Erythrocytes or red blood cells are the most common type of blood cells which transport oxygen to different organs through blood vessels. The specialised structure of RBC’s that performs specific functions are: -
The cell mem
ane is made up of lipids and proteins that performs physiological functions like cell stability and deformability.
RBCs are biconcave and oval disks that lack nucleus and most organelles so that they can...
