Product Description
This 48-slide teaching PowerPoint presentation pack covers 4.A.2 (Differentiation), 4.A.3 (Organelles), 4.A.4 (Organ Systems) 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).

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:

4.A.2 - Differentiation

The structure and function of subcellular components, and their interactions, provide essential cellular processes.

a. Ribosomes are small, universal structures comprised of two interacting parts: ribosomal RNA and protein. In a sequential manner, these cellular components interact to become the site of protein synthesis where the translation of the genetic instructions yields speci?c polypeptides.

b. Endoplasmic reticulum occurs in two forms: smooth and rough.

     - 1. Rough endoplasmic reticulum functions to compartmentalize the cell, serves as
          mechanical support, provides site-speci?c protein synthesis with membrane-bound ribosomes
          and plays a role in intracellular transport.
     - 2. In most cases, smooth ER synthesizes lipids.

c. The Golgi complex is a membrane-bound structure that consists of a series of ?attened membrane sacs (cisternae)

     - 1. Functions of the Golgi include synthesis and packaging of materials (small molecules) for
          transport (in vesicles), and production of lysosomes.

d. Mitochondria specialize in energy capture and transformation.

     - 1. Mitochondria have a double membrane that allows compartmentalization within the mitochondria and
          is important to its function.
     - 2. The outer membrane is smooth, but the inner membrane is highly convoluted, forming folds
          called cristae.
     - 3. Cristae contain enzymes important to ATP production; cristae also increase the surface area for
          ATP production.

e. Lysosomes are membrane-enclosed sacs that contain hydrolytic enzymes, which are important in intracellular digestion, the recycling of a cell’s organic materials and programmed cell death (apoptosis). Lysosomes carry out intracellular digestion in a variety of ways.

f. A vacuole is a membrane-bound sac that plays roles in intracellular digestion and the release of cellular waste products. In plants, a large vacuole serves many functions, from storage of pigments or poisonous substances to a role in cell growth. In addition, a large central vacuole allows for a large surface area to volume ratio.

g. Chloroplasts are specialized organelles found in algae and higher plants that capture energy through photosynthesis.

     - 1. The structure and function relationship in the chloroplast allows cells to capture the energy available
          in sunlight and convert it to chemical bond energy via photosynthesis.
     - 2. Chloroplasts contain chlorophylls, which are responsible for the green color of a plant and are the key
          light-trapping molecules in photosynthesis. There are several types of chlorophyll,
          but the predominant form in plants is chlorophyll a.
     - 3. Chloroplasts have a double outer membrane that creates a compartmentalized structure, which supports its
          function. Within the chloroplasts are membrane-bound structures called thylakoids.
          Energy-capturing reactions housed in the thylakoids are organized in stacks,
          called “grana,” to produce ATP and NADPH2, which fuel carbon-?xing reactions in
          the Calvin-Benson cycle. Carbon ?fixation occurs in the stroma, where molecules of CO2
          are converted to carbohydrates.

4.A.3 - Organelles

Interactions between external stimuli and regulated gene expression result in specialization of cells, tissues and organs.

a. Differentiation in development is due to external and internal cues that trigger gene regulation by proteins that bind to DNA

b. Structural and functional divergence of cells in development is due to expression of genes specific to a particular tissue or organ type.

c. Environmental stimuli can affect gene expression in a mature cell.


4.A.4 - Organ Systems

Organisms exhibit complex properties due to interactions between their constituent parts.

a. Interactions and coordination between organs provide essential biological activities.

     - Stomach and small intestines
     - Kidney and bladder
     - Root, stem and leaf

b. Interactions and coordination between systems provide essential biological activities.

     - Respiratory and circulatory
     - Nervous and muscular
     - Plant vascular and leaf
