Review: Cell Processes1) Why do cells divide?2) Which cells divide more frequently?3) Which cells divide less frequently?4) What stage are they in if they are not dividing?5) What’s the name for “programmed cell death”?6) Which cell division process creates IDENTICAL cell copies?

Cell Pictures/LabelingYou need to draw how the cell looks for EACH stage of mitosis

You must LABEL the parts of the cell

However, for each additional picture, you only need to label the NEW structures

Interphase*NOT part of mitosis(precedes mitosis)Includes stagesG1, S, G2Cellular contents(organelles) copiedGenetic material(chromatin) copiedChecked for mistakes

Chromatin is NOT condensed into chromosomes yet (can’t see it)

Prophased

Early Prophase Late Prophase• Chromatin condenses into

chromosomes (now visible)• Nucleolus disappears• Nuclear envelope breaks

down• Two centrosomes form the

mitotic spindle (made of microtubules)

• Centrosomes pushed to opposite poles of cell

Prophase*

Metaphase*Easiest stage to identifyChromosomes aligndown the middleKnown as the “metaphaseplate”Microtubules attach to centromeres of sister chromatids

Anaphase*

Early Anaphase Late Anaphase

• Microtubules pull sister chromatids apart(centromeres split)

• Individual chromosomes are pulled by the microtubules to opposite poles

(same amount of genetic material on either side)

Telophase*Begins after chromosomesstop movingSpindle fibers dissolveChromosomes uncoil and revert to chromatin formA new nuclear envelop forms around each chromatin mass (forms nucleus)Nucleoli appearCleavage furrow forms at site of metaphase plate (middle)

Cytokinesis*Cytoplasm pinches inward (at the cleavage furrow) until cell is divided into two identical daughter cellsOrganelles reappearBoth cells can nowstart the process again…

Interphase (Begins Again)

d

Plant Cells*Process in plant cells is different than in animal cellsNo cleavage furrow... Why not??Main difference is:Cell wall prevents cleavage furrow. Instead, vesicles from the golgi apparatus fuse in the center of the cell to create a cell plateCell plate grows outward until it reaches the cell membrane, that then separates into two daughter cells

Mitosis ModelingYour job for today and tomorrow is to make a model of mitosisYou will create images of each stage by drawing the cell stage on paper and using pipe cleaners as chromosomesYou will use a smartphone to take a picture of each stage, and email them to yourselfYou will download those images and create a Google slides (only!!) presentation, with one phase for each slideYou will write the description of each phase on each slideYou will save the presentation as a PDF and email it to me, so I can print the slidesYou will then create a poster with the printed images to model mitosisWe will complete this same process with meiosis post-vacation, so leave space! (AND CHOOSE PARTNERS WISELY!)

I am about to explain a new class “roject.” A fairly detailed explanation is

required, so please do NOT talk while I am speaking. Also, hold ALL questions

until the end. Thank you

Title of Stage

Label

Logistics3 people per group, you may choose your group but CHOOSE WISELYYou may NOT work alone, though if your group members do not show up, you will continue soloYou have the rest of today, and another full class period to work on this (to finish slides)You will have 15 minutes on Thursday to cut out the slides and put the posters togetherThen, you will take a quiz on mitosis

Couple more things…Make sure at least one member of your group has a smartphone with wifi/ 3G so pics can be emailed (and make sure this person is reliable and will be here tomorrow!)This presentation is uploaded to the website already, so you can use these slides to guide your drawingsThere are additional resources on the website to help youDue to the large volume of ink/paper needed to print your slides, only groups who have a COMPLETE, ACCURATE, and VISUALLY APPEALING presentation will get their slides printed. Those who do not meet these qualifications will not receive credit. These people may take notes from the textbook while others work.

Finally…Make sure I “ok” each phase before taking your final pictureYour presentation slides should be clear, concise, and easy to read from far awayIf you do not finish on Tuesday, you MUST come after school on Tuesday to finish so I can print your slidesYou are all responsible for your own grade. If your group members slack off, do not let that bring you down. Instead, rise above and do their work in addition to yours. It sucks, but it’s a part of life. Choose your partners wisely.YOU ARE IN CHARGE OF YOUR OWN EDUCATION!

Recap- Create image (one 8 x 11 paper) for each stage- Take a picture of each stage and email it to yourself- Download images and put each one on their own Google slide- Title each slide with the stage, and provide a brief description- Save presentation as a PDF and email it to Ms. Gately- On Thursday, cut out slides and create a poster
