Investigates plant reproduction: concepts, terminology, types of reproduction, pollination, and seed development and germination. Includes questions, review, and a quiz.
(Source: DCMP)
Part of the "Visualizing Cell Processes" series. Includes the following modules: "Mitosis: Chromosome Condensation," "Mitosis: Stages," "Cytokinesis," "Meiosis," "Nucleotide Structure and Bonding," "Replication Enzymes," "Replicating the Strands," "The Twisting Problem," and "Proofreading and Repair."
Discusses the diverse reproductive strategies of microorganisms. One of nine segments in a series, with all nine available on a DVD.
Human beings, like every living organism, are driven by two inherent needs: to survive, and ultimately, to reproduce. To accomplish the goals of survival and reproduction, we have inherited bodies crafted by evolution so that every individual human organism is an organic super factory, a living machine made up of systems that process fuel, build products, repair damage, expel waste, and defend against invaders. Introduces the complex physiological systems of the human body: muscular movement, digestion, circulation, respiration, nerves, glands, immunity, and reproduction. Also, illustrates and explains the cellular basis of life and the importance of carbon in organic chemistry.
Students investigate important processes including photosynthesis, reproduction, growth, and germination. They also learn how these processes relate to the structure of plants. Important terminology includes flower, pistil, stamen, pollen, pollination, and reproduction.
Provides an overview of how attraction, desire, and sexual coupling lead to conception. Covers the physiological events underlying the process of reproduction. NOTE: graphic content.
The delicate interplay of hormones is responsible for all the events of reproduction. Many other body processes are controlled and coordinated by these chemical messengers. The role hormones play in response to a sudden emergency-the "fight or flight" reaction-is also reviewed.
Why does everything turn yellow in spring? Pine trees produce yellow pollen every year at this time. This annoying ritual is necessary for pine trees to reproduce. Part of the "Seasonal Science" series.
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. This video discusses virus structures and why a host is critical for viral reproduction. Part of "The Amoeba Sisters" series.
Students are introduced to basic concepts related to heredity. Special emphasis is placed on some easy to understand human traits that are inherited. Concepts and terminology discussed include: characteristics, traits, and inheritance.
Explains what is normal for boys and girls at puberty: the biological facts of physical maturation, the timeline for growth for both sexes, the normal feelings of self-consciousness, the need for good personal hygiene, why mood swings happen, and preparation of the body for human sexuality and reproduction.
Part of the "The Biology Classics" series. The cross-eyed flatworm, planaria, is both scavenger and predator, depending upon opportunity. Details food-seeking behavior, the flatworm's feeding method, locomotion (produced by a carpet of cilia), internal anatomy, and reproduction through the remarkable process of regeneration.
NOVA takes an in-depth look at scientific breakthroughs in reproductive science. Discusses in vitro fertilization (IVF) and examines some of the latest techniques in treating infertility: cytoplasmic transfer, micromanipulation, and egg donation. Presents the challenges and risks of infertility and treatments. Raises ethical questions about the implications of reproductive technology.
In this episode, host Emily Graslie meets with Dr. Robert Martin to discuss the evolution of human birth. They also highlight the progress being made to reduce mortality rates related to giving birth. Part of "The Brain Scoop" series.
After explaining the differences between butterflies and moths, examines the complete metamorphosis of the zebra longwing butterfly. Looks at a butterfly's anatomy; purpose of specific body parts; and how they have adapted for camouflage, gathering food, reproduction, and pollination. Explains the butterfly's unique place in the survival of all species.
Host Emily Graslie discusses harmful plants related to the holiday season. Some of the plants highlighted include mistletoe, poinsettia, holly, and pine. Part of "The Brain Scoop" series. Please note this title makes references to plant and human reproduction.
All living organisms share several key characteristics or functions. When combined, these characteristics serve to define life. In this episode, Petunia and Pinky discuss several of the characteristics of life. Part of "The Amoeba Sisters" series. Please note: This title contains discussions on sexual reproduction.
Petunia and Pinky introduce viewers to bacteria in this episode. They discuss bacterial structure, reproduction, and how not all bacteria are bad. Other topics covered include endospores, plasmids, and bacteria transformation. Part of "The Amoeba Sisters" series.
Guides deaf women through the first trimester of their pregnancy. Discusses medical considerations, nutrition, fitness, pregnancy, rights to an interpreter, and other issues. Also, covers what changes your body may experience by month to month. Lists 129 words in sign language. Hosted by Deanne Bray of "Sue Thomas: F.B. Eye" and Missy Keast.
