GUIDELINES FOR BIOLOGICAL DRAWINGS
The list below is a set of guidelines that are required used by Biology students in Tasmania for drawings.
- Plain, unlined paper should be used.
- Use a sharp pencil. Never use coloured pencils or pens. Everything on the page should be in pencil, even label-lines labels, and the title and its underlining. It is recommended that an HB or H is used.
- Do not draw the circle of field of view.
- All drawings should be as large as possible within the space available. Never use less than half a page, and if possible use a whole page. Leave space at the sides for labels or annotated comments, and leave space above the drawing for a title.
- When drawing lines do not lift the pencil from the paper until the line is completed. Lines completed with ‘one stroke’ are required, not a succession of half hearted ‘scratchiness’.
- Do not shade or colour unless instructed.
- Drawings should include several complete cells. Additional incomplete cells may be drawn to show the relationship between cells in the tissue.
- Label-lines should be in pencil and must touch the object labeled and preferably point to the middle of that object. They should be horizontal (where possible) and never cross each other. Arrows are not appropriate.
- Labels must be written horizontally in pencil, and must be accurate and spelt correctly. Do not write the plural for single objects: petal not petals, mitochondrion not mitochondria.
- Each drawing should have a full underlined title in pencil. The title should be above the drawing and may include the following where appropriate:
a) the name of the organism
b) the type of section
c) the location of the cell
d) magnification used when viewing / drawing the cell(s)
e) any stain that has been used.
For example: Human cheek cells stained in methylene blue
Viewed at x100 magnification
- Do not draw structures that cannot be seen; for example, mitochondria and ribososomes that are beyond the power of school / college microscopes or that cannot be seen due to lack of staining.
- When drawing cells indicate the dimensions of an average cell on your diagram by either a scale bar or the actual magnification of your drawing.
