BIOLOGICAL DRAWINGS

THE GOOD THE BAD

BIOLOGICAL DRAWING RULES

• Use unlined paper.• Draw in pencil.• Always print.• Print the title in capital letters above the

field of view.• Drawings and individual structures should be

drawn to scale.• When labeling structures on the drawing, do

not cross over lines to point to structures.

BIOLOGICAL DRAWING RULES

• Try not to erase.• Write the name of the specimen below the

field of view. When using the scientific name of an organism in places other than the title, the first part of the name is capitalized and the second part of the name is not. Underline the scientific name.

• Below the name of the organism and to the right, print your name and the total magnification.
