 Even when you appear to stop growing, cell division ___  Average adult has about ___ cells!  Cells take on different ___ and ___ to perform different functions  Called ___  This is why your stomach cells and bone cells are different in appearance and function

 When your group is called, you will come up to the red table and look at the four prepared microscope slides.  Be careful not to touch the stage or slide because it is perfectly focused on what you need to be looking at! You may move the adjustment knob to focus only!  Choose a cell in your specimen that you feel shows the cell division process occurring. In the table below, draw what you observe and record 3 detailed observations for each specimen you view.

 In your notes section, create the following table: MicroscopeDrawing of 1 Cell3 observations 1 2

 Answer the following questions under your data table  Predict what was happening to the parts of the cell in the specimen you observed. What evidence and prior knowledge do you have to support this?  Were you able to see multiple examples of cell division taking place or only one? Why do you think this was the case? Did this surprise you?

 While you are waiting for your group to be called up, turn to page 80  Begin reading chapter 3.2  Record each phase of mitosis and describe the defining characteristics for each phase  When you complete your observations, try to identify each of these phases in your specimens

 _____is the normal ___ and division of a cell  Only ___ cells undergo ___  This process can take anywhere from a couple of hours to a couple of years depending on the type of cell!

Cytokinesis

 _____  Part of the cell cycle when a cell is ___  In this phase, DNA begins to ___ and the cell grows ___ its size  There are ___ in between DNA replication  Think of this as the “___” part of the cell cycle

 ___  Part of the cell cycle during which the nucleus ___.  ___  DNA in the nucleus ___ to create chromosomes ▪ Chromosomes are ___ connected together  Nucleus membrane ___

 ___  Chromosomes line up in the ___ of the cell to get ready for mitosis

 ___  Chromatids ___ from the ___, making two separate chromosomes  These chromosomes go to ___ ends of the cell

 ___  A ___ forms around each group of chromosomes  Chromosomes ___ and DNA goes back to their looser form  When the cells split into two, we call each new cell a “___”

 Occurs___ after mitosis  The ___ in the cell  In ___ cells, a ___ forms in the center of the dividing cell  This ring contracts, pulling the membrane inward and pinching the cell into two  In ___ cells, a ___forms in between the two new nuclei  This plate becomes a cell wall

Purpose: To demonstrate understanding of each process of mitosis, as well as the transition from one phase to the next. Using PowerPoint or Prezi, create a flip book to show the processes of mitosis. Provide detailed explanations about each phase and include a picture to show what each phase looks like.

 You will be working with a clock buddy  Person 1:  Research details for interphase, prophase, and metaphase  Provide descriptions and images  Research images for transitional phases between these  Person 2:  Research details for anaphase, telophase, and cytokinesis  Provide descriptions and images  Research images for transitional phases between these

Requirement1 pt3 pts5pts Sequence More than half of the phases are out of sequence (3+ are not). Transitional phases may or may not be included Almost all phases are in the proper sequence (1-2 are not).

Presentation is not neat or organized. There are few spelling or grammatical mistakes (1- 3). Presentation is neat and organized. There are no spelling or grammatical mistakes. Presentation is neat and organized.

 DNA- a chemical that contains genetic information for an organism’s growth and functions. It is a double helix structure and contains nucleotides.  Chromosome- the physical structure in a cell that contains the cell’s genetic material… DNA wraps around proteins to create them  Chromatid- one half of a chromosome; one set of DNA that is then duplicated

 Interphase- the part of the cell cycle during which a cell is not dividing  Prophase- the part of mitosis in which the nuclear membrane disappears and chromosomes form  Metaphase- the part of mitosis in which chromosomes line up in the center of the cell and spindle fibers attach to the chromosomes

 Anaphase- the part of mitosis in which chromosomes are pulled apart and brought to opposite ends of the cell  Telophase- the part of mitosis in which a new nuclear membrane forms around each new set of DNA and chromosomes uncoil  Cytokinesis- the division of the cytoplasm in a cell undergoing mitosis

 Cell Cycle- The continuous pattern of a cell’s life, including growth and replication  Mitosis- The part of a cell’s life in which the nucleus divides to create two identical cells  Asexual Reproduction- the process by which a single organism produces offspring that have the same genetic material

 ___  One organism produces one or more new organisms that are ___ to itself and live___ of it  Organism that produces new organisms is called the ___  New organisms are called ___

 ___  A form of ___ reproduction that occurs in ___ cells only  Produces two completely ___  In unicellular organisms, ___ are the same thing!

 ___  Both ___ cells can reproduce by budding  An organism ___ on its body, which forms into a new offspring  Buds can either ___ to parent or ___ when they get too big  Identical genetic material to parents

 BEk BEk

 In this lab, you will be exploring asexual reproduction in yeast.  As we learned, yeast reproduces by budding, which means that it creates buds that eventually will fall off once the buds reach a certain size. These buds will become more yeast cells that live independently of its parent cell

 “I predict that……. because……”  What are you predicting to see under the microscope?  How quickly will you see this?  How many will you see?  Why do you think you will see this?

 Person 1  Get a microscope and paper towel  Person 2  Get a slide and specimen

 tPNs tPNs (start at 0:25)

 ___  New tissue growth at a site of a wound  Can either mend a wound or form a new offspring
