Homework….
Find a diagram of a plant and animal cell
(textbook or internet).
Redraw both cells and label them fully.
Research the difference between a
prokaryote and eukaryote cell. Put
your info into a suitable table.
Due: 15/09
Title: Cells…
Lesson Objectives:
1. Can I name and identify cell
organelles? Grade C
2. Can I compare and contrast
prokaryotic and eukaryotic cells?
Grade B/A
Starter: Study your pics of
cells….then label mine…
The type of cell you are currently
familiar with:
Cell theory….
The basic principles of the cell theory are:
 All organisms are made of cells that resemble
each other by having internal structures and a
boundary
 These cells are always formed by the division of
pre-existing cells
 Cells contain inherited information which
determines their activity
 Given suitable conditions, cells are capable of
independent existence
Can you name the 7 characteristics all living things
share?
Cell Structure…

Given these principles of cells, biologists recognise
two types of cellular structure:
Prokaryotic cells (‘before the nucleus’)
 Eukaryotic cells (‘with a nucleus’)


Virus particles do not fulfil the criteria of the cell
theory and so are regarded as being non-cellular.
Some texts may refer to their structure as being
‘akaryotic’ (without a nucleus)
