Your name

On the back of this page:
1. Prepare a diagram of one (or more) onion skin cells;
2. Label the cell wall and the nucleus, list their definitions and functions;
3. Include a scale bar indicating the approximate size of an average cell. Scale bar is a short line labeled with particular size, like “0.1 mm”. Using scale bar only, everybody understands what is the real size of the object on the diagram.
Please show your math! (6 pts)
What is the length and width of a cell from an Elodea leaf? How big is a chloroplast from an Elodea leaf?(Hint: the same way as you “fitted” Elodea cells into field diameter and then calculated cell size, you need to “fit” chloroplasts into the cell which size you already know.) Please show your math! (3 pts)
Which cells are bigger: cheek cells or onion skin cells? Please show your math! (3 pts)
