Drawings & diagrams

Asked to ID specimens on exams (not today’s specimens- just used for practice)

Draw all specimens & provide scale bar for study purposes

Practice formal drawing today- follow guidelines closely

Scale bar calculations

Example formal drawing:• Drawing left, labels right• Drawing = 2/3 page• Use pencil & unlined paper• No shading or crosshatching.

Shade by stippling• Do not draw EVERY cell- draw

representative sample• Only draw what you can see• Scale bar with calculations• 2 (+) structures labeled

– Touches structure– Lines not crossed– Singular/ plural names– Use ruler
