Assignment: Microscopy, Cells, Mitosis, and Meiosis

1. Draw arrows and label the different parts of the microscope using the word bank provided.

Arm                               Fine Adjustment
Base                              Light Source
Condenser                      Nosepiece 
Course Adjustment          Objectives  
Diaphragm                      Stage
Eyepiece                         Viewing Head

2. Calculate the total magnification if ocular (eyepiece) magnification is 10x and the objective power is 50x.

3. Circle the correct answer that accurately describes a characteristic of Eukaryotic cells.

Cell size:               Small                                   Relatively Large
Nucleus:               Has nuclear envelope             No nuclear membrane
DNA:                    More than 1 long, linear         Single circular chromosome
Organelles:           None                                    Many membrane bound organelles
Cell division:         Fission or budding                  Mitosis or meiosis

4. Name two differences between Animal and Plant cells.

5. True or False: Mitosis is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets, in two separate nuclei.

6. True or False: Meiosis results in daughter nuclei containing only ½ the number of chromosomes as the the parent nucleus.

7. Order the phases of Mitosis using the numbers 1-4.
