Cell Division: Mitosis and Cytokinesis
An inspiring and challenging 20 minute video for high school or university biology students. This video starts by emphasizing the central importance of cells in life, and that living cells can only arise from other living cells by cell division. After distinguishing mitosis (nuclear division) from cytokinesis (cell division), several…
Living Cells: Structure, Function, Diversity
Living Cells features greatly expanded coverage of subject matter and extensive additional footage when compared to the original video tape of 1992. The vivid, high-magnification images introduce students to a variety of cells, cellular activities, and subcellular organelles. The video is organized into 24 chapters on specific topics such as…
The Dynamics and Mechanics of Mitosis
Mitosis requires cells to organize numerous jumbled chromosomes and then separate them with absolute fidelity into two equal groups. How this extraordinary process is accomplished is still poorly understood. This video reveals the events of mitosis at a level of detail usually seen only in research laboratories. In addition, two…
Diatoms: life in glass houses
Diatoms are an extraordinarily successful group of organisms and their many thousands of species have diversified and specialized so as to occupy every environmental niche. Part of their success derives from their unique protective cell walls, beautifully elaborate structures made of pure silica. However, living inside walls made of this…
Remarkable Plants: The Volvocales and Chlorococcales
The Volvocales and Chlorococcales share a common ancestry from a cell type exemplified by Chlamydomonas. Using live cells, this video shows how simple evolutionary trends working on Chlamydomonad ancestors have generated diversity and complexity. In Volvocalean evolution, unicellular ancestors became multicellular (e.g., Volvox) by daughter cells adhering after division. Concurrently,…
Remarkable Plants: The Oedogoniales
The Oedogoniales are remarkable filamentous green algae. Their method of cell elongation is unique, utilizing a donut-shaped ring of soft wall material which is stretched to form the new daughter cell. While Oedogonium is a simple filament, the related Bulbochaete and Oedocladium are branched and Bulbochaete differentiates long hair cells.…
Reproduction in the Red Algae
Reproduction in the red algae is unique. No flagellated stages are ever formed, and it is generally assumed that the various reproductive spores are inert. This video demonstrates that spores in many species are actively motile, either by gliding or amoeboid activity. This limited power of movement may turn out…
The Kingdom Protista - The Dazzling World of Living Cells
For convenience, biologists divide living organisms into five "Kingdoms": the Monerans (bacteria and cyanobacteria), Protists, Fungi, Plants, and Animals. The Kingdom Protista includes a vast array of tiny eukaryotic cells that lead complex and extraordinary lives far from the eyes of most humans; a dedication to microscopy is vital to…
