- Biological drawing
- Drawings should always be in pencil. Fine detail cannot be represented accurately unless the pencil has a sharp point.
- The outlines of any structures should be drawn but there should be no colouring or shading.
- The relative sizes of the structures drawn should be accurate.
- If required, the drawn structures should be labelled, using label lines that do not cross or obscure the drawing, with brief annotations about their functions or interrelationships.
- The drawing should have an explanatory title and an indication of the real size of the structures drawn or of the magnification used.
- Cell drawing
- show accurately the components of individual cells observed using an optical microscope. The drawing should be detailed but should not show more than two or three cells.
- Tissue map
- purpose of a tissue map is to show the location and extent of tissues in an organ or in a whole organism. Cellular detail of any of the tissues should not be shown. Instead, the outline of each tissue should be drawn. This often presents a problem, since cell differentiation is seldom discrete.
- Body plan
- Following dissection, a morphological drawing should provide a lifelike representation of the main body parts exposed by the dissection. A small part drawn well is much better than a full drawing drawn badly.
- Errors when drawing
- Cell outline
- crossing lines
- tissue with too much detail
- hanging lines
- over casual
- sketch rather than a drawing
