Cell Cycle -  The stages the cell go through as it grows and divides

Interphase- The longest stage of the cell cycle; main stages of growth and preparation for cell division.

S Phase-  Synthesis phase; Stage of the cell cycle, when DNA is replicated

G1- Gap phase 1, Stage of the cell cycle where organelles are replicated

G2- Gap phase 2, Stage of the cell cycle where the cell undergoes its final growth before division

Mitotic phase-  Stage of the cell cycle where the cell's nucleus is divided

Cytokinesis-  Stage of the cell where the cytoplasm is divided and two new daughters cells are formed

Mitosis-  comprised of 4 stages :prophase, metaphase, anaphase, telophase;  this process ensures that each new cell being made has a nucleus with the correct amount of chromosomes.

Meiosis- A 2 set process that comprises the 4 stages of Prophase, metaphase,anapahse, telophase but completes this cycle twice.  This process ensures that each cell formed has half the number of chromsomes as the parent cell; creating gametes in the process. 

The students will be able it list and define the stages of the cell cycle and meiosis

The students will compare and contrast meiosis and mitosis, their function and processes

The students will explain why the cell cycle is necessary for an organism to survive

The students will explain how gamates are formed

5 class periods and 1 lab

• PowerPoint Presentation
• Projector
• Poster board
• Markers

Instructional Procedure:

Day 1: 

 Objectives will be written on the board for this lesson

 Discuss the point of the cell cycle why it is important for growth and repair of our bodies

 Students will take guided notes on the cell cycle

Students will be drawing a cell cycle filling in the different sections of the cycle and what occurs during
that cycle.   Color coding the different areas as to easily see the different sections.

Day 2:

 Review the cell cycle sections by having the students come to the Smart board and filling in any section of the cycle they remember and its function.

Students will take guided notes on Mitosis, a specialized section of the cell cycle.  

Students will come up with a mnemonic device to remember the 4 stages of the cell cycle, they will be encouraged to share their device with the class. 

Home work:  Read article on Cancer and answer guided reading questions. 

Day 3: 

Discuss the Cancer article as a class.  Have the students share some interesting facts they learned from the article.    The students will be making the connection between Mitosis and tumors.   We will also discuss the difference between cancerous and non-cancerous tumors.   Chemotherapy drugs and their role in cancer
suppression and how they affect the cell cycle and mitosis will also be discussed. 

Show the students animations of Mitosis in action.  Making sure the students understand that mitosis
occurs in plants and animal cells but that there is a difference in binary fission and mitosis. 

Homework:  Students will work on identifying the different stages of mitosis, by completing the book study guide on mitosis.

Day 4: 

Review homework

Discuss the goal of mitosis is 4 cells with 23 pairs of chromosomes all identical to each other, for growth and repair.   Meiosis has a different goal, why else would we need to make more specialized cells.   Have the student brainstorm about what they think the goal of Meiosis is and why it is important.   After working for a couple minutes, I will tell them one goal of Meiosis is to make cells that are genetically different from each other, and continue to get their feedback as I give them more goals of meiosis.  

We will make a chart of goals of mitosis vs. the goals of Meiosis.

Guided notes on Meiosis

Day5: 

Students will work in pairs to create a poster of mitosis and meiosis.  It will state the differences and the similarities of each process.

Students will divide the poster into three sections.   They will draw and label each stage of mitosis and meiosis.    Labels should include centromere, centrioles, spindle fibers, nuclear envelope, chromosomes and chromatids. 

The middle column should be left blank that is where the students will write their bullet points on the similarities of the cycles and the differences between the cycles.    They can use any classroom resources that are available to them.
