Product Description
-- Included in 3.A - Inheritance Package --

This 48-slide teaching PowerPoint presentation covers 3.A.2 (Cell Division) in the AP Biology (2015) curriculum. Each slide includes the 'Essential Knowledge' being covered as well as key terms that students should make note of (editable).

This unit has been divided into two sections:

1 - Cell Cycle & Mitosis
2 - Meiosis

The presentations themselves contains minimal information as they are intended to be used with teacher guidance. There are 'Video' slides throughout which link to relevant and informative YouTube content. The slides are formatted to be visually pleasing and to also print well for handouts or revision. Please see the preview file (first 8 slides) for an idea of the aesthetic and level of detail in the presentation. The relevant 'Essential Knowledge' can be found below.

Suggested Use:

I have had success using these presentations to review topics after students have been exposed to the material at home. I typically have the class read relevant material (book, site, etc.) and then watch the videos the day before introducing a topic. During the class period, I use the slides to structure the discussion around the AP Bio Essential Knowledge objectives. The remaining class time is spent reinforcing the knowledge or working on activities geared toward the 'Learning Objectives'.

**These presentations are based on the AP Biology Course Guide and does not follow any textbook

As always, please let me know if you have any suggestions for improvements. These are always a work in progress!

The Essential Knowledge covered includes:

3.A.2 - Cell Division

In eukaryotes, heritable information is passed to the next generation via processes that include the cell cycle and mitosis or meiosis plus fertilization.

a. The cell cycle is a complex set of stages that is highly regulated with checkpoints, which determine the ultimate fate of the cell.

     - 1. Interphase consists of three phases: growth, synthesis of DNA, preparation for mitosis.
     - 2. The cell cycle is directed by internal controls or checkpoints. Internal and external signals provide stop-and
          go signs at the checkpoints.
          -- Mitosis-promoting factor (MPF)
          -- Cancer results from disruptions in cell cycle control
     - 3. Cyclins and cyclin-dependent kinases control the cell cycle.
     - 4. Mitosis alternates with interphase in the cell cycle.
     - 5. When a cell specializes, it often enters into a stage where it no longer divides, but it can reenter the cell
          cycle when given appropriate cues. Nondividing cells may exit the cell cycle; or hold at a particular stage
          in the cell cycle.

b. Mitosis passes a complete genome from the parent cell to daughter cells.

     - 1. Mitosis occurs after DNA replication.
     - 2. Mitosis followed by cytokinesis produces two genetically identical daughter cells.
     - 3. Mitosis plays a role in growth, repair, and asexual reproduction
     - 4. Mitosis is a continuous process with observable structural features along the mitotic process. Evidence of
          student learning is demonstrated by knowing the order of the processes (replication, alignment, separation).

c. Meiosis, a reduction division, followed by fertilization ensures genetic diversity in sexually reproducing organisms.

     - 1. Meiosis ensures that each gamete receives one complete haploid (1n) set of chromosomes.
     - 2. During meiosis, homologous chromosomes are paired, with one homologue originating from the maternal
          parent and the other from the paternal parent. Orientation of the chromosome pairs is random with respect to
          the cell poles.
     - 3. Separation of the homologous chromosomes ensures that each gamete receives a haploid set of
          chromosomes composed of both maternal and paternal chromosomes.
     - 4. During meiosis, homologous chromatids exchange genetic material via a process called “crossing over,” which
          increases genetic variation in the resultant gametes.
     - 5. Fertilization involves the fusion of two gametes, increases genetic variation in populations by providing for
          new combinations of genetic information in the zygote, and restores the diploid number of chromosomes.
