Instructions: 1)Using a microscope and prepared slides of onion roots, find specimens undergoing each of the five stages of the cell cycle (four stages of mitosis (PMAT), and interphase). 2) Prepare a properly labelled, and titled biological drawing of each stage. Use at least half of a page for each drawing. 3) Label the magnification you used when studying the cell in the upper right hand corner of each drawing. 4) Provide an appropriate title, centered, at the bottom of each drawing that describes the stage of the cell cycle drawn, e.g. An Onion Cell in Anaphase. 5) Label as many organelles as you can. Use a straight edge to draw the lines from your label to what it is referring to.
Some Things to Remember About Proper Biological Drawings Always use a pencil Use a ruler or straight edge for labels The drawing should take up at least half of a page Write the magnification at the top right hand corner of the drawing Write a descriptive title, centered, at the bottom of the drawing Only use blank, white paper.
