To get a sense of the importance of size in microscopy, see the following on Cell Size & Scale:

(Just drag the bar right to increase, and left to decrease, the magnification.
Note, also, the scale that appears in the upper left hand corner!)

Resolution:

In your study of cells you may very well come across images similar to those belowSome things to consider:

Animal Cell

Plant Cell

Bacterium

All Images are from an INTRODUCTION TO CELL AND VIRUS STRUCTURE
created by Molecular Expressions, a wonderful website created by faculty at Florida State University

Prior Knowledge:

We will be using this to determine what we are LOOKING at, so that we might actually SEE it!  What is actually visible with a Compound Light Microscope will act as the prior knowledge that will allow us to comprehend what we are viewing through our eyepiece.   This just leaves one question:

Animal Cell

Plant Cell

Bacterium

Cell Membrane Cell Wall It's SO SMALL,
all you will see is
The Cell Envelope
(Composed of,
from the inside/out
a cell membrane,
a cell wall,
and in some
species, a capsule.)
Cytoplasm Cell Membrane
Nuclear Membrane Cytoplasm
Nucleus Nuclear Membrane
Chromatin
(Its in there,
even if you can't
see the detail!)
Nucleus
Chromatin
Chloroplast

Drawing Tips:

Before you start to practice your drawings, you should refer to the TIPS ON MAKING GOOD DRAWINGS, which can be found on my HOW TO USE A MICROSCOPE PROPERLY page.  In addition to tips on labeling, you must, above all, remember to:

Apply your knowledge of cell structure to your drawings!
An unlabeled drawing is nothing more than scratches on a piece of paper!

Drawing Cell Images From Light Microscopes:    C O M I N G     S O O N !

  1. Practice first by making pencil drawings of the following images.

  2. Include the appropriate labels on your drawings.

  3. Once you have completed steps 1 & 2 above, you should check out the labeled drawings below to see how those drawing should appear.

O.K. Folks! You are Now Ready to Try to Draw On Your Own, Using Real Microscopes & Slides!

HAVE FUN!
