Microscopic Observation of
Cells
Part Two
•Observing cells under a microscope can be confusing –
you need to try and identify basic features like the
nucleus first.
•Once you have focused on your slide and can see your
cells clearly you need to make a drawing of them.
•There are rules for this ……………… !! 
Rules for Microscope Drawings
•Drawings should be large and clear.
•Use a sharp pencil for the drawing and the labels.
•Use a ruler to draw labelling lines.
•Don’t sketch, use clear single lines.
•Don’t just copy the diagram in your text book!
•Don’t use arrows for labelling.
Drawing Plant Cells
This is a plant cell as it would be seen
under a microscope.
The nucleus has been stained so you can
see it more clearly.
What structures can you make out?
What else would you see in a typical plant
cell?
This is the sort of drawing you would
make of a cell like this.
What is wrong with this drawing?
What are palisade cells and where are they found?
Palisade cells are the main photosynthesising cells in a
leaf. They are usually packed with green chloroplasts.
They are found in the upper layer of the leaf.
Revision: Structure of a Plant Cell
Can you complete the labels on this diagram?
Drawing Animal Cells
This is human cheek cell viewed through a
microscope.
What structures can you make out?
This is the sort of drawing you would
make of this cell.
What is wrong with this drawing also?
