CELL DIVISION

A. Draw a picture of one cell, show it dividing into two cells, then four, etc. Calculate how many cells you will have after:
  • one cell division
  • two cell divisions
  • three cell divisions
  • four cell divisions
What pattern do you notice is happening with each cell division?
Calculate how many cells you will get in one minute if the first cell divides every five seconds.


B. Read page 102 in your textbook about cell division.

C. Watch the following videos about cell division
    • Simulation of Cell Division Shows how one cell divides over and over again to make many cells!
    • Basic Cell Division Shows how the nucleus divides first and then the cytoplasm divides (Cytokinesis).
    • Mitosis of a Lung Cell Shows an electron microscopic video of the nucleus from the cell of lung tissue dividing. 
    • Mitosis of a Blood Lily Shows an electron microscopic video of the chromosomes pairing up in the nucleus of the cell of a Lily plant dividing.
    D. Write a paragraph summarizing what cell division is. 
    1. Use transitional words like first, then and finally to organize your paragraph.
    2. Include the following words in your paragraph:
    • cell division
    • mitosis
    • nuclei
    • chromosomes
    • DNA
    • cytokinesis

        DNA and CHROMOSOMES

        1. Brain Pop DNA
        2. What are Chromosomes?
        3. Number of chromosomes in living organisms
        4. Size of Living organisms in cm - Do an internet search. (Hint-type name of organism and facts or size in search bar - i.e. elephant facts or elephant size) 
        5. Conversion Calculator
        Copy the following table. Make 10 rows and choose about 10 organisms to research. The ones listed are just suggestions.
        Use the links above or do an internet search to fill it out information about the number of chromosomes vs the size of living organisms.
        Name of ORGANISM Plant or Animal   Size in
        centimeters
        (cm)          
        Number of Chromosomes Predicted Actual Number of Chromosomes   
        Human
        Homo Sapien            
                                                                               
        Cat
        Felis catus





        Dog       Canis lupus familiaris





        Cow Bos primigenius





        Bean  Phaseolus




        Potato

        Solanum tuberosum





        Fast plant
        Brassica rapa























        1. How close were your predictions?
        2. Add to this data chart and make a graph comparing the size of an organism with number of chromosomes it has. You may hand draw the graph or do it on a spreadsheet in Microsoft Excel.
        3. Is there any correlation to size?
        4. Do plants or animals have more chromosomes? Is there any correlation?

          MICROBES IN THE HUMAN BODY

          Make a table with the following three columns. Fill it out by visiting the link Bacteria in your body that keep you healthy.

          1. Places in your body where it is normal for bacteria to live.
          2. Names of bacteria that live in each place in your body.
          3. Purpose (or function) of each bacteria in your body.

          Cells Alive! How Big is a virus? a bacteria? a protist? a cell? Visit this website to see relative sizes of microorganisms.

          Click on the links to the following microbes. Find 1-2 examples of each classification of microbe: Protist (Protazoan), Bacteria, and Virus.

          Make a table with a column for each type of microbe. Each column should include:
          1. Drawing of microbe
          2. Features of each microbe (shape, size, how it moves, where it lives)
          3. Disease caused by microbe or usefulness of microbe.
