Knowing the appropriate ways of drawing a biological diagram can surely improve your overall performance in BIOLOGY and also enhance your understanding about the subject. During my teaching, I observed that, many students performing well in the descriptive components of BIOLOGY, but as soon as biological diagrams crop up in their examinations or quality of homework. They develop a tendency to struggle for making diagrams. If you want to score more in biology, you must read the following advised and principles or can say the technically-feasible rules of drawing a biological diagram.
Drawing Biological Diagrams: A few rules to follow.
1. No need for Improvisation-
You can’t use your creative brain to draw biological diagrams on your answer sheet. You should draw what you see in the textbook, NOT what you WANT to see. So please don't imagine anything.
2. Use just right Pencil-
Make sure you use a good quality pencil for your diagrams. Extra bold or 2H lead pencils are more advisable. And remember NEVER draw your diagrams with a pen.
3. Simplicity is what’s preferable-
Try to make your diagrams as simple as possible, but must be Accurate in its general proportions, and should be precise in its overall.
4. Keep away from shading-
Shading specific areas of a diagram might look aesthetic to the eyes and you, but this train just not acceptable in biology. Hence, the advice is to AVOID at all costs. Represent darker areas of an object with stippling or dots. Do not shade any areas of the diagram. colouring or graying of the areas should be strictly prohibited.
5. Drawings must be executed on an unlined sheet-
Biological drawings must be done on unlined sheets or plane sheets, for more authenticity. This principle should be followed particularly when you are drawing a diagram for your biology lab copy or record.
But don’t worry about your board exam you get lined copy and you have to draw on that lined sheet.
6. Biological drawings should be conspicuous for easier comprehensibility-
Avoid crowding components of the diagram. A biological drawing must bear all relevant parts that are conspicuous enough to the human eye. It should also be large enough to current the whole complicated background details of the diagram to the observer.
7. Labeling and positioning
As far as labeling is concerned, follow the following rules as closely as possible for more efficiency:

- Labeling should be done in a column at the right-hand side of your page. Try to maintain alignment to the best of your abilities.
- Always use a scale for drawing the lines used for labeling purposes, and it’s more advisable to keep those lines parallel to one another.
- The lettering used for labeling should be kept in a horizontal alignment. Try to avoid vertical lettering unless you are specifically instructed or constrained to do so.
- Keep your lettering neat and intelligible such that the observer can understand it in a jiffy. For easier comprehensibility, may use block letters for lettering purposes.
- Do not use the plural form when identifying a single part or object.
A few more worthy mentions…
All biological drawings should be titled. Write the title of the diagram in capital letters and center it
Try to draw the diagram on a single stroke of the pencil. Multiple strokes need to be avoided at all possible costs.
Use sharp single lines to represent an object. Do not use soft lines, characteristic of sketches
