Animal cells have some of the same structures and organelles that plant cells have, but not all
of them.
a
Write P beside each structure in the table that is only found in plant cells. (3 marks)
b
Choose one of these structures and explain why it is not found in animal cells. (1 mark)
The diagrams show three specialised plant cells.
Draw and complete a table like the one to
the right to show the adaptation and function
of each cell type. (6 marks)

Spirogyra is an alga. It is made up of cells joined by their cell walls to form long filaments. If a
single cell is detached from the filament it can survive and grow to form a new filament.
a
Are the cells specialised? (1 mark)
b
Say which piece of information you used to decide whether the cells are specialised and
explain how it led you to your answer. (2 marks)
