cells?
Success Criteria:

Create your own fungal cell slide using the heat fixing
method

Successfully view a fungal cell and draw a scientific
drawing of it

Describe the structure of a fungal cell
What are Fungi?

Heat Fixing a slide
Before staining, the sample must be heat fixed. This
process accomplishes three things:

kills the organism

firmly attaches the smear to the microscope slide

allows the sample to more readily take up the stain

Once a sample is heat fixed to a microscope slide, there
are many staining techniques that can be used to view
the cell. A simple stain is the use of one dye to increase
contrast between the specimen and background when
viewed through a microscope.
Instructions
Safety: Long hair must be tied back and all safety
equipment worn at all times. Report any glass
breakages to the teacher. Only use the tongs to
handle the slides over the flame
1.
Set up the Bunsen Burner Safely
2.
Take one drop of the yeast solution and place it on your
glass slide
3.
Using the wooden tongs, pull the glass slide through the
flame of a Bunsen burner (1-2 times). The specimen
should not come into contact with the flame (specimen
on top, flame on the bottom).
4.
Place one drop of Iodine on the slide
5.
Using the wooden tongs, pull the glass slide through
the flame of a Bunsen burner (1-2 times). The specimen
should not come into contact with the flame (specimen
on top, flame on the bottom).
6.
Place a slide cover on top of your specimen and view
under microscope

sure to complete a
full scientific diagram of a
