All lesson are recorded & stored . If necessary these will be viewed by Mrs Wilson and your Head of
Year.
Inappropriate behaviour will result in a phone call or a home visit during the lesson and you will be
removed from the lesson by the teacher.
At the start of the lesson either, open an e-mail addressed to victor.oczadly@astreadearne.org, have
a word document or have pen & paper available to make notes/complete the lesson tasks.
Send your work to your teacher at the end of each session (victor.oczadly@astreadearne.org). In the
case of hand written work, take a photo & email that.
Please note: if you fail to follow these expectations, you will not be able to access Dearne Home Learning
and will attend school for face to face teaching.

5. Challenge
Covert these
measurements
0.5cm = ? mm = 5mm
23mm = ? μm = 23000μm
15mm = ? μm = 15000μm
200μm = ? mm = 0.2mm

4. Last Year
Name an organ system.
Give 3 organs within it.
Success is the result of preparation, hard
work and learning from failure
What do you recall about these
specialised cells?
Are they all the same? Plant root hair cells
Red Blood cells
Nerve cells
Muscle cells
Sperm cells
Specialised Cells
21 February 2023
To explore how cells
become
differentiated to
become specialised
State some examples
of specialised cells
Describe the process of
differentiation
• Sperm , Nerve,
Muscle, Root Hair,
Xylem
• Differentiate
• Specialised
Relate the structure of
the specialised cells to
their function
How do we go from this unspecialised
to this specialised cell?
Cell
differentiation
Cell differentiation
This process involves the cells structure
changing to allow the cell to complete a
particular job it will now be known as a
specialised cell. Once an animal cell is
differentiated it will lose the ability to
repeat the process whereas in plants a
special section called a meristem allows the
cells to differentiate over and over.
Can you define these key terms using the information above?
Differentiation
Specialised
Specialised Cells
We now know that
cells are different.
Why?
1. BETWEEN SPECIES: Different types of organisms live in different
environments. Their cells are adapted to survive in those
environments.
(Write examples on your sheet – think animal vs. plant vs.
bacteria)
2. WITHIN A SPECIES: Multi-cellular organisms’ cells carry out
specific jobs. We say that they are specialised. This means that
they need to be a certain shape and have special structures and
proteins that help them do the job/function properly.
(Write examples of different organs/cell types on your sheet).

find, a cell profile, a spider diagram
You must include name, function, adaptations
