What different types of cell are there?
Starter:
list as many types of cell as you can.
What different types of cell are there?
Learning Outcomes
 list a variety of proteins, outlining their appearance and function
 describe how body cells in an organism contain the same genes
 recall that many genes in a particular cell are switched off
 outline the one gene  one protein theory

• Specialised cell – a cell that has differentiated
to have features that allow it to do a particular
job.
• Specialised cell – the most important cell in
your body.
• Specialised cell – a type of cell that makes cells
special.

If all our cells are genetically identical why do we
have so many different types of cell?
Think – Pair – share
How many proteins are found in this cell?
Stem Cell

Switching genes on and off
Stem Cell
Muscle Cell

Skin Cell
Brain Cell
How
many
proteins
does
each cell
have?
Stem cells and differentiation.
Cells that make up embryos are called stem
cells. These are unspecialised but can turn into
any type of cell if they get the correct message.
A muscle cell is the same as a heart cell but
different genes have been turned on/off making
it do different things.
Proteins
If you remove all the water from a human body,
90% of what remains is protein.
What types of protein are there?
Read the information, highlight the key words
and use it to complete the questions.
6 mark Q
Humans all develop from 1 cell. Explain in detail, how it is
possible for a human to end up with so many types of cell.
Task: answer this question and write a marking scheme to go
with it.
(1 mark will be for SPAG)
Make a revision card for
specialised cells.
