Assignment title
Identifying structures and functions in different cells
The purpose of this assignment is to demonstrate an understanding of cellular organisation of a cell. Learners should
be able to link the organelles present within a cell to its tissue type and function. They should be able to compare and
contrast the different tissue types in terms of their structure and function and organelles observed.
Scenario
You have just started work in a cytology lab in the local hospital. Your work includes the analysis of blood and tissues
samples to identify diseases and other problems. You have been issues with samples of slides of different tissues
and cells that have been incorrectly labelled and you have been asked to identify and analyse the slides.
Task 1
P5: Describe the key structures and functions of a eukaryotic and prokaryotic cell
You have been given a diagram of a prokaryotic and eukaryotic cell. Your task is to label all the observed organelles
and explain the structure and the function of each of the organelles.
Due date:
Task 2
This provides evidence for P5
P4: Interpret electron micrographs of different types of tissues
You have been issued with electron micrographs to interpret. Label the cells and organelles on the micrograph and
explain what each micrograph is showing.
Due date:
Task 3
This provides evidence for P4
P3: Record accurately observations of different
types of tissues from a light microscope
M2: Explain how the relative presence of
different cell components influences the
function of tissues
3a: You have been issued with slides o f the following tissues: epithelial, connective, nervous, muscular Observe
each of the slides under a microscope and draw and label what you can see. (Remember to only draw what you see,
not what you expect to see). Label each of your drawings with the correct tissue type.
3b: From the drawings that you have completed write a report for your supervisor explaining the function of each of
the slides. Explain how the presence of particular organelles influences the function of the tissue. Explain what
organelles you would expect to see in each of these tissues and how the organelles enable the tissues to perform
particular functions.
Due date:
Task 4
This provides evidence for P3 + M2
D2: Compare different tissues with similar functions in terms of their structure and functions
Write a report to compare and contrast different tissues types within the body. Your report could be on cardiac,
smooth and skeletal muscle or endocrine and exocrine glands. Include in your report the functions of the tissue, the
organelles that are present that allow it to function and how it differs from other tissues.

Criteria
reference
To achieve the criteria the evidence must show that the learner is
able to:
P3
Use a light microscope in accordance with good practice to draw and label
samples of tissue types
P4
Use electron micrographs and identify and draw the cell organelles
P5
Produce a short description of the structures and functions of cell components.
M2
Explain cell differentiation and its importance in the formation of tissue types.
Learners should be able to identify different types of tissues from their
observations of electron micrographs and explain how the presence of certain
numbers of cell components influences the function of tissues
Compare different tissues, in terms of their structure, that have similar functions,
clearly describing the differences between the tissues and explaining how both
tissue types perform similar functions.
