Description
Absorbing facts about the 11.3 million species on Earth might cause your brain to burst! You need to take in huge timelines (the first life on Earth formed 3.8 billion years ago), huge numbers (your body is made up of trillions of cells), and even huger mysteries (why species go extinct).
How can all these big numbers and concepts make more sense? Infographics! The charts, maps, and illustrations in this book tell a visual story to help you better...
Description
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...
Description
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...
Description
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..
Description
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..
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.”...
Description
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
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..
Description
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
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 flower to witness dynamic events such as pollination, gametophyte formation, fertilization, embryo formation and fruit formation are seen as spectacular computer simulations..
Description
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...
Description
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...
Description
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...
Description
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...

Description
Living things depend on other living things in order to survive. This is called interdependence. This engaging book explores the symbiotic and competitive relationships that exist between interdependent organisms. The accessible text is perfect for young scientists. Beautiful, full-color photographs on every page make this an exciting introduction to the way organisms interact with each other to fulfill their needs. This important life science topic...
17) Biochemistry and Molecular Biology: How Life Works: Episode 21,Hormones, Stress, and Cell Division
Description
Cellular communication depends on specific molecular interactions, where the message and the receiver are biomolecules. Follow this process for signaling molecules such as the hormones epinephrine, adrenalin, and epidermal growth factor, which stimulates cells to divide. Cellular signaling is like the children's game called telephone, except the message is usually conveyed accurately!
Description
See how the cognitive changes of aging relate to the biological changes discussed in the previous lectures. It turns out that regions of the brain associated with processing speed, executive function, and episodic memory are more susceptible to aging, which may explain why these cognitive functions are particularly susceptible to decline.
Description
RNA is more than simply a copy of the DNA blueprint. Focus on the synthesis of RNA, covering how it differs from DNA replication. Also learn how human cells shuffle their genetic code to make about 100,000 different proteins using fewer than 30,000 coding sequences. Finally, see how knowledge of transcription occurring after death helps forensic scientists establish the time of death accurately.
20) Biochemistry and Molecular Biology: How Life Works: Episode 25,DNA and RNA: Information in Structure
Description
Advance into the last third of the series, where you cover molecular biology, which deals with the biochemistry of reproduction. Zero in on DNA and how its double-helix structure relates to its function. Then look at the single-stranded RNA molecule, which is a central link in the process, "DNA makes RNA makes protein."_x009d_ Also consider how viruses flourish with very little DNA or RNA.
