<strong>B09</strong> <strong>Microviewer</strong> <strong>Plant</strong> <strong>Mitosis</strong> April 06, 2011<strong>Microviewer</strong> Activity: <strong>Plant</strong> <strong>Mitosis</strong>Name:___________________Instructions:1. Read each section of the microviewer booklet carefully.2. Answer the questions on the worksheet in complete sentences.3. Draw proper microscopes sketches (in pencil only) in the circle provided.4. Record the magnification of each photomicrograph in the space provided.Introduction:The process by which cells divide and produce exact copies of themselves is called mitosis. The eightslides in this microviewer set show onion root tip cells going through the five stages of mitosis.Slide 1. Stage 1: Interphase1.a) Draw a diagram of cell A in the space provided at the left.This cell represents stage 1 of mitosis and is calledinterphase ("between phases"). It is often called the"resting stage", but the cell is not actually resting.(include magnification)b) Complete the following sentences regarding two thingsthe cell is doing during interphase:• The cell is carrying on all• The chromosomes makeSlide 1. Early Stage 2: Early Prophase1. c) Draw cell B. This is the early parts of the divisionprocess called prophase.(include magnification)d) Complete the following sentences regarding two thingsthat are happening to the chromosomes in prophase:• The chromosomes have become• At this stage of development they are called
<strong>B09</strong> <strong>Microviewer</strong> <strong>Plant</strong> <strong>Mitosis</strong> April 06, 2011Slide 2. Stage 2: Prophase2.a) Draw the large cell near the centre of the slide.(include magnification)b) Describe what has happened to the chromosomes.c) Describe what has happened to the shape of thenucleus.Slide 3. Stage 3: Metaphase3.a) Draw cell C. This represents the third stage of mitosisand is called metaphase.(include magnification)b) Complete the following sentences regarding thechromosomes:• The chromosomes have developed into• The chromosomes have moved toSlide 4. Early Stage 4: Early Anaphase4. a) Draw cell D. This represents early stage 4, earlyanaphase.(include magnification)b) Complete the following sentences regarding thechromosomes:• Each chromosome pair has• As the split rods move away,c) What do the spindle fibres appear to do?

This is in stage 4, called anaphase.(include magnification)b) Complete the following sentences regarding thechromosomes:• The cell has now produced two duplicate sets of• The two new sets of chromosmes are beginning toSlide 6. Late Stage 4: Late Anaphase6. a) Draw cell F. This is in late stage 4, late anaphase.(include magnification)b) Complete the following sentences regarding thechromosomes:• The movement of the two complete sets ofchromosomes toward the poles• The number and kind of chromosomes in each of htetwo sets isSlide 7. Stage 5: Telophase7.a) Draw cell G. This cell is in the final stage of mitosiscalled telophase.(include magnification)b) Complete the following sentences regarding thechromosomes:• The two sets of chromosomes in the cell have• Individual chromosomes can• Each mass will• The faint line in the middle will become

This is in late stage 5, called latetelophase.(include magnification)b) Complete the following sentence regarding the cell:• The cell wall isSlide 8. Stage 1: Interphasec) Draw both cells marked A These cells have finishedmitosis and are back in the resting stage, or interphase(stage 1) (include magnification)d) Complete the following sentences regarding the newdaughter cells:• The new nuclei can be seen with• The cell wall has developed fully and• The two cells will nowComplete the following summary table on the following stages of <strong>Mitosis</strong>http://highered.mcgrawhttp://www.pbs.org/wgbh/nova/baby/divi_flash.html http://www.biology.arizona.edu/cell_bio/tutorials/cell_cycle/cells3.htmlProphaseStage Sketch DescriptionMetaphaseAnaphaseTelophase
