The Cell: Structure and Function

Chapters 3 & 4 Objectives

Informational Link 1: animation showing the relationship among the e.r. and Golgi

Activity 1 "Cell Transport" select "Passive Transport" (read and take notes on the animation; BE PATIENT- the animations take a while to load and complete)


Activity 2 "Active Transport" select "Active Transport"

                (Download accompanying worksheet for Activity 2 "Active Transport" here)


Transport animations:


    the sodium potassium pump (select sodium potassium exchange)

 Tying it all together:

    The neuron: basic neuron design and the action potential (select "Action potential propagation...")

    The synapse: (select "Chemical Synapse" ) shows what happens at the synapse highlighting diffusion, ion channels, exocytosis, cell communication, vesicle formation (think back to the endomembrane system!)

    The neuromuscular junction: reviewing the concepts in the above link but also shows gated channels and the stimulation of muscle by a neuron (select "Function of the Neuromuscular Junction")


Informational Link 2: animation showing phagocytosis

Informational Link 3: animation applying the use of various transport mechanisms (diffusion, exocytosis), membrane receptors, vesicles in the functioning of a neuron (select "Chemical Synapse") (remember the sodium-potassium pump resets the neuron so that it can "re-fire")

PowerPoint presentation from class (cell structure only)

Mouse Party- a look at how concepts learned in chapters 3 and 4 can be applied to the understanding of drug addiction

Chapter Objectives for chapters 7 & 8

Activity 1: Download the instructions for the activity here.

                Web Site #1

                Web Site #2

Activity 2: "Concept 6: Chloroplast Structure".  After labeling the diagram, download a copy to hand in.  On your downloaded copy, indicate where the light reactions occur and where the Calvin cycle occurs.  You might also want to try your hand at taking the self-quiz.  Many of these questions you should be able to answer.

Photosynthesis Homework Questions

Animation showing absorption of light by PS 2 and PS 1  (By the way PS = PhotoSystem NOT Play Station!) (Correlates to figs. 8.6 and 10.10 in packet)

Animation showing the transfer of electrons from PS 2  to PS 1 and the production of ATP and NADPH (Correlates to the "electron transport system" arrow of fig. 8.6)

Animation showing the overall relationship between the light reactions and the Calvin cycle (Correlates to fig.10.4 in packet)

Lab Results: Chromatography


Cell Division:

Animation showing DNA coiling to from chromosomes

Animation showing chromosome replication

Animations for mitosis:  1. Mitosis (by John Kyrk)

                                      2. more mitosis  (maybe a little easier to follow)

                                      3. and even more mitosis

                                      And in case the ones above don’t work don’t work….

DNA Structure and Replication:      

Animation 1 showing DNA replication (nice and simple)

Animation 2 showing DNA Replication  Please allow some time for this site to load.   This site goes into the chemistry a bit more that you need.  Pay attention to the summary points that get presented at the top of each section, these help a lot.  You also have a benefit of taking little quizzes to check for understanding.
