1

A
True
2
Q
What is a microscope
A
Instruments that allow us to see a clearer image of cells.
3
Q
How would you calculate Magnification?
A
Magnification= Image size ÷ Actual size
4
Q
What is Cell Fractionation?
A
Is a process where cells are broken into individual organelles
5
Q
Before Cell Fractionation can begin, what conditions must the cells be in?
A
The solution must be:
1. Cold, Isotonic: to reduce enzyme activity that can break down the organelles
2. Water: to have the same water potential so the cell does not burst or shrivel up due to osmosis
3. Buffered: so the pH does not fluctuate and change the structure of the organelles
