Biological Drawing Rules to Follow & Practise
Neatness is really important, make sure that all of your lines are complete (especially for cell membranes and walls), ensure that if you are drawing multiple cells that each cell has its own cell membrane, not sharing with the one next to it. No sketching, solid lines only and no shading at all.
Ask your teacher to see some exemplars of acceptable and not acceptable biological drawings
