The Virtual Cell : Are you a high school student or teacher? If you are either, then you might want to check out this page first.

Cell Biology at Kimball's Biology. Includes animal cells, the cell cycle, chloroplasts, chromosomes, golgi apparatus, mitosis and meiosis, the nucleus, photo-synthesis, polyploidy, ribosomes, stem cells and more.

Cells & Origins : This page discusses pre-evolutionary concepts and hypotheses regarding the origin of the universe and the first forms of life (abiogenesis). Together with a second page, the development of cellular life and microscopy is explained.

Molecular Biology of the Cell : This is the 3rd Edition of this textbook. Includes introduction to the Cell and Evolution of the Cell.

Molecular Cell Biology : by Harvey Lodish, et al., Fourth Edition.

Cell Structure and Function : This is a comprehensive reference website with links to excellent resources.

Cell Biology Laboratory Manual : 15 chapters, 10 appendices.

The Biology Project: Cell Biology : From the University of Arizona, includes problem sets and tutorials.

Histology Tutorial : Review subjects at this college of medicine website and take quizes such as this one: Cellular Structure Quiz.

ESG Biology Hypertextbook : Supplements course materials with tools for learning introductory molecular biology. Includes enzyme biochemistry, Krebs cycle, photosynthesis, Mendelian genetics, gene expression, recombinant DNA and immunology.

Biophysics Textbook Online : This site will eventually hold about 500 peer-reviewed chapters. Included is material for which no good teaching text now exists. This is not introductory material.

Cell and Molecular Biology Online : A reference website for students and professionals, it goes far beyond introductory matters.

The WWW Virtual Library: Cell Biology : From Harvard.
Extensive resources in all aspects of cell biology.

A Web Atlas of Cellular Structures : Displays a series of light and confocal micrographs of a variety of subcellular structures and organelles. Useful for people interested in cytology who do not have access to advanced imaging technologies or biological expertise.

WWW Cell Biology Course : While still a work in progress, the completed pages tend to be easy to understand by someone at the introductory level. Lots of links also.

Prokaryotes : Introductory essays on prokaryotic ecophysiology and biochemistry, biotechnology, prokaryotic organisms and archive.

Novel Cell Particles : Vaults were discovered in 1986 and their precise function remains unknown. Because there are thousands of them in all cells of higher organisms and because the particle has been highly conserved throughout evolution, it is likely that vault function is important to all cells.

The Krebs Cycle : The citric acid cycle, also called the tricarboxylic acid (TCA) or Krebs cycle, is the final common catabolic pathway for the oxidation of fuel molecules.

Cells Alive : The photo galleries, video cams, articles and other resources at this website may be what you are looking for.

Cellular Biology Images : Diagrams with explanations represent important processes of biotechnology.

Stem Cell Primer: The National Institute of Health resources about Stem Cell Research.

Stem Cell Hope for Parkinson's: Scientists are closer to finding a cure for Parkinson's disease using special "master cells" taken from embryos. Researchers have used the cells successfully to treat mice and rats which mimicked symptoms of the human condition.

Stem Cells Promise Liver Repair: UK scientists have shown how cells from transplanted bone marrow can turn into liver tissue.

Bush's Stem Cell Decision: Full text: As a result of private research, more than 60 genetically diverse stem cell lines already exist. They were created from embryos that have already been destroyed, and they have the ability to regenerate themselves indefinitely, creating ongoing opportunities for research.

NIH Human Embryonic Stem Cell Registry: The registry of human embryonic stem cell lines approved by the NIH includes 67 lines at 11 institutions, and describes characteristics for some.

Animal Cell Map : The Eukaryotic Cell has membrane bound organelles that allow special functions to be carried out in little compartments, separated from the rest of the cytoplasm.

Plant Cell Map : Plant cells have two new organelles not found in animal cells. Click on boxes to find out more about these organelles.

Peering Into the Cell Nucleus : Movies and animations of the cell nucleus in action, with links to research resources.

Self-Replication: Even Peptides Do It
By Stuart A. Kauffman. From Nature.

Endosymbiotic Theory of Eukaryote Evolution was first proposed by Lynn Margulis in her 1981 book "Symbiosis in Cell Evolution".

Origins of the Eukaryote Cell : Aspects of the Autogenous and Endosymbiotic Hypotheses regarding cell origin.

Evolution of the Bacterial Flagella : Michael Behe nominates the bacterial flagella as "irreducibly complex" and unable (or unlikley) to be produced via evolution. A microbiologist responds.

Giardia lamblia : Biology & microscopy of what some scientists have called a missing link in the evolution of eukaryotic cells from prokaryotic cells.

The Origin of Cellular Life
Sidney W. Fox, a man some colleagues say should have won the Nobel Prize, showed how living cells can be formed from inanimate material.

Microscopy Primer : Bibliography and links to other microscopy sites. This site has albums of microscopic photos at Molecular Expressions Photo Gallery.

History of the Light Microscope

Microscopy Articles : This library contains material published in Micscape Magazine, the monthly magazine of Microscopy-UK, since 1995. Articles are grouped into areas such as biology, botany, insects and marine animals.

Electron Microscope Images
MicroAngela explores the microscopic world with colorized images from electron microscopes at the Univ. of Hawaii. Check out things that grow on and in you and all around you.

From The Lives of a Cell: Notes of a Biology Watcher: by Lewis Thomas [1974]. "Man is imbedded in nature. The biologic science of recent years has been making this a more urgent fact of life. The new, hard problem will be to cope with the dawning, intensifying realization of just how interlocked we are. The old, clung-to notions most of us have held about our special lordship are being deeply undermined." See more at Amazon Books.

Organelles as Organisms: by Lewis Thomas. We seem to be living through the biologic revolution, so far anyway, without being upheaved or even much disturbed by it. Even without being entirely clear about just what it is, we are all learning to take it for granted. It is a curious, peaceful sort of revolution, in which there is no general apprehension that old views are being outraged and overturned.
