In the animal world, the easiest way to avoid being eaten is to avoid being seen. What are Camouflage and Mimicry? examines animals that use unique colorization to avoid their predators - or to sneak up on prey! So highly developed is the camouflage of some animals, that they are virtually impossible to see. Examples include:
• spots and stripes that blend into the shadows
• bright colors that warn of toxic poisons
• animals that look like rocks,...

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. Witness dynamic events such as pollination, gametophyte formation, fertilization, embryo formation and seed germination.....

Description
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 zoospore is large and multiflagellated. Sexual reproduction is oogamous and either “macrandrous” or “nannandrous.”...

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 Appendices show mitosis in a classical system, the diatom cell, and some experiments on living cells that illustrate why...

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 sugars. Animations also illustrate the forms of leaves and how they are modified for dry and aquatic habitats..

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 as spore formation, spore release, prothallus formation, sperm release, fertilization and embryo growth..

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 rigid, refractory material creates many problems. Just how diatoms circumvent these problems provides the major...

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 female stems where gametangia (sex organs), sperm release, fertilization and embryo development are illustrated..

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 actin, microtubules, and flagella.. The Living Cells video offers a most convenient way of accessing beautiful...

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 see them in all their splendor. This video is a unique resource introducing the viewer to a considerable range...

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, they evolved various advanced characters (e.g., differentiation...

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 animal cells are shown undergoing mitosis and a 3D animation shows how the mitotic spindle is assembled. Chromosomes...

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 to be of considerable significance in survival strategies (e.g. dispersion, optimization of a germination site).. Sexual reproduction is also...

Description
The waters off the West African coast are a menacing red, full of algae thick enough to stand on in places. In nearby villages, mysterious deaths start to occur--and the panic mounts. But before an alarm can be sounded, the sea currents shift, the algae vanishes, and the deaths stop. Everyone is relieved when things return to normal, and local government officials are happy to sweep the publicity nightmare under a rug. An American biological researcher,...
