===Meaning===
Use a [[microscope]] to make labelled [[diagram]]s of [[plant]] and [[animal]] [[Cell (Biology)|cells]] with a [[Magnification Scale|magnification scale]].
===Method===
#Place a [[sample]] of onion [[Cell (Biology)|cells]] on to a [[slide]].
#Place a drop of 0.01M [[Iodine Solution]] onto the [[Cell (Biology)|cells]].
#Place a cover slip on the [[Cell (Biology)|cells]] and use tissue paper to remove any excess [[Iodine Solution|iodine solution]] from the edges.
#Place the [[slide]] onto the [[stage]] of the [[microscope]] and focus the image.
#Note the [[magnfication]] of the [[Eyepiece Lens|eyepiece lens]] and the [[Objective Lens|objective lens]].
#Sketch a [[Cell (Biology)|cell]] including a [[Magnification Scale|magnification scale]] to indicate how much larger you drawing is than the actual [[Cell (Biology)|cell]].
#Place a [[sample]] of animal [[Cell (Biology)|cells]] on to a [[slide]].
#Place a drop of [[Methylene Blue]] onto the [[Cell (Biology)|cells]].
#Place a cover slip on the [[Cell (Biology)|cells]] and use tissue paper to remove any excess [[Methylene Blue]] from the edges.
#Place the [[slide]] onto the [[stage]] of the [[microscope]] and focus the image.
#Note the [[magnfication]] of the [[Eyepiece Lens|eyepiece lens]] and the [[Objective Lens|objective lens]].
#Sketch a [[Cell (Biology)|cell]] including a [[Magnification Scale|magnification scale]] to indicate how much larger you drawing is than the actual [[Cell (Biology)|cell]].
