Download BTEC Unit 1 Assignment 2 Task 4 M2 Comparing Cell Components

P2 Record accurately observations of different types of
tissues from a light microscope
P4 Interpret electron micrographs of different types of tissues
P5 Describe the key structures and functions of a eukaryotic
and prokaryotic cell
M2 Explain how the
relative presence of
different cell
components
influences the
function of tissues
D2 Compare different
tissues with similar
functions in terms of
their structure and
functions
Keywords - cell membrane; cell wall; nucleus; nucleolus; cytoplasm; mitochondria; ribosome; endoplasmic
reticulum (smooth and rough); Golgi body; lysosome; vesicles
Assignment 4 Comparing Cell Components
L/O How are cells in different tissues specialised?
Starter – Why are cells different?
Comparing Cell Structures for function
• Microvilli cells are found in the gut and are adapted to
absorb small molecules from the gut into the blood stream
• Neurons are adapted to sending electrical impulses along
them and then signals from their synapse
• Examine the images of these two cells and describe, explain
and compare their internal structure in terms of their
function
Keywords - cell membrane; cell wall; nucleus; nucleolus; cytoplasm; mitochondria; ribosome; endoplasmic
reticulum (smooth and rough); Golgi body; lysosome; vesicles

Comparing Cell Structures for function
• Define the term specialised cell
• Draw a diagram of each cell
• Write a paragraph describing the function of each cell.
• Write one paragraph describing what cell components
(organelles) are present in each cell and explain why they
are needed
• Find, print and label an electron micrograph of a neuron
and a microvilli cell

• For M2, learners must briefly 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. For
example, consideration of the effect a large number of
mitochondria in a tissue may have on its function.
• Different tissue types should be considered.
