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,…
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…
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…
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…
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.…
The Secret Life of Leaves
Three dimensional animations, supported by aurthoritative narrations, explore the leaf surface and explain the functioning of the guard cells. The viewer is then taken inside the leaf to see the photosynthesis and conducting cells. Witness the dynamic events of guard cell movements, gas exchange and the transport of water and…
Remarkable Regeneration
Salamanders can regenerate entire legs and tails to replace ones they have lost, while deer shed their massive antlers and re-grow them from a few remaining cells each year. How do these creatures regenerate entire body parts and why is it not possible for all animals to do the same?
The Secret Life of Pines
Combining images of living plant stages with computer simulations allows you to easily bridge the gap between the familiar plant and the micro-environment contained within it. Three dimensional animations take you inside the pollen cone and the seed cone to see reproductive structures such as sporangia, gametophytes and the archegonia.…
The Secret Life of Ferns
Combining images of living plant stages with computer simulations allows you to easily bridge the gap between the familiar plant and the micro-environment contained within it. Three dimensional animations take you in and around reproductive structures such as the sorus, sporangium, and antheridium and archegonium. You see dynamic events such…
The Secret Life of Mosses
Combining images of living plant stages with computer simulations allows you to easily bridge the gap between the familiar plant and the micro-environment contained within it. Computer animations take you inside a clump of moss plants to illustrate external structure. You are then transported inside the tips of male and…
Superlife: Genetic Manipulation
Designing Life. Man has been doing it for over 10,000 years. You may not be aware of it, but we are surrounded by "Superlife," life-forms manipulated by Man. Superlife looks at the stories of how these super organisms came to permeate our planet, and how the latest science is pushing…
