Part 3: Making Microscope Drawings:
Instructions for Microscope drawings:
1) Draw what you actually see.
2) Center your drawing/ diagram on the page and leave room of labels.
3) Make your drawing big enough so you can see all the important details.
4) Drawings should be accurate representation of what you observe
5) Proportions should be accurate.
6) Labels: all parts of your diagram must be labeled accurately using vertical or horizontal label lines
and simple clear descriptions.
7) Drawing should have a title, magnification (or scale bar), names of structures.
Plant Cell.
Instructions: Look at plant cell under low magnification(5x) and then under a higher magnification (either
high (40X) or medium (10X)) Draw your plant cell in the boxes below. Be sure to label all the visible
organelles, and follow the above instructions about “Making Microscope Drawings”
Plant Cell – Low Power (5X)
Plant Cell – med (10X) or high power (40X)
Animal Cell.
Instructions: Look at animal cell under low magnification(5x) and then under a higher magnification
(either high (40X) or medium (10X)) Draw your animal cell in the boxes below. Be sure to label all the
visible organelles, and follow the above instructions about “Making Microscope Drawings”
Animal Cell – Low Power (5X)
Animal Cell – med (10X) or high power (40X)
Bacteria/ prokaryote Cell.
Instructions: Look at Bacteria cell under low magnification(5x) and then under a higher magnification
(either high (40X) or medium (10X)) Draw your bacteria cell in the boxes below. Be sure to label all the
visible organelles, and follow the above instructions about “Making Microscope Drawings”
Bacteria Cell – Low Power (5X)
Bacteria Cell – med (10X) or high power (40X)
