Paul Andersen explains how the cell cycle is used to create new cells. The creation of identical diploid daughter cells, through mitosis, is described. The creation of unique haploid daughter cells, through meiosis is also described. The importance of cyclin and cyclin dependent kinases to regulate the cell cycle is included.

Posted below is the handout activity sheet that goes with this video.
Paul Andersen explains how genes are regulated in both prokaryotes and eukaryotes. He begins with a description of the lac and trp operon and how they are used by bacteria in both positive and negative response. He also explains the importance of transcription factors in eukaryotic gene expression.
Paul Andersen explains the major plants structures. He starts with a brief discussion of monocot and dicot plants. He then describes the three main tissues in plants; dermal, ground and vascular. He also describes the plant cells within each of these tissues; epidermis, parenchyma, collenchyma, sclerencyma, xylem and phloem. He describes both primary and secondary growth in plants. He finishes the podcast with a discussion of double fertilization in plants.
Paul Andersen explains how nutrients and water are transported in plants.
He begins with a brief discussion of what nutrients are required by plants and where they get them.
He shows you dermal, vascular and ground tissue in monocot and dicot roots, stems and leaves.
He then explains how water is pulled up a tree in xylem and how sugar is pushed in a plant through phloem.
Short video to get the basic key concepts down.
Explore the process of osmosis in this updated Amoeba Sisters video! Video features real life examples of osmosis, important vocab, and introduces concept of water potential and turgor pressure in plant cells.
Hanodut for video: Anderson water potential
In this video Paul Andersen defines water potential and explains how it can be calculated in a simple system. He explains how water can moved through osmosis and break down the two major parts of water potential (solute potential and pressure potential).
He finishes the video with a sample calculation of solute potential. You NEED to KNOW this!!!
Paul Andersen starts by defining transpiration as evaporation off of a leaf. He then describes how a potometer can be used to measure the rate of transpiration in different environments.
You will be doing a modified transpiration experiment.
This is a helpful study guide for plant hormones.
Very short with illustrations.
This is from U of A.
Paul Andersen explains how feedback loops allow living organisms to maintain homeostasis.
He uses thermoregulation in mammals to explain how a negative feedback loop functions. He uses fruit ripening to explain how a positive feedback loop functions. He also explains what can happen when a feedback look is altered. Diabetes mellitus is caused by an alteration in the blood glucose feedback loop.
Definately need to know this for the AP EXAM!!!!
Paul Andersen surveys the circulatory system in humans. He begins with a short discussion of open and closed circulatory systems and 2, 3, and 4-chambered hearts. He describes the movement of blood through the human heart and the blood vessels. He discusses the major components of blood and the cause of a heart attack.
Paul Andersen shows you how to use a sphygmomanometer to measure the systolic and diastolic blood pressure. The the describes the elements of the laboratory portion. The temperature is gradually lowered and the respiration rate of a goldfish is measured.

Helpful tips/ concise information
A 'MUST READ' to prepare for exam for those students who want to do well.
Paul Andersen starts with a brief description of feeding methods. He then details all of the major parts within the human digestive system. This tour starts in the mouth, move down the esophagus, through the stomach, small investing, colon and rectum. He explains how all of the major macromolecules are digested and absorbed by the body.
This is the handout for: video_ Digestion__ Anderson
this is the handout for the Anderson Nervous system video.
You need to know the nervous system for the AP Exam.
Paul Andersen begins this podcast with a discussion of brain lateralization and gives a brief demonstration of tests that were performed on split-brain individuals. He then discusses the major parts of a neuron and explains how action potentials are generated using voltage-gated ion channels. He explains how neurotransmitters transmit messages across a synapse and how these messages can be either inhibitory or excitatory.
