Research in biology would be impossible without a common framework for grouping and distinguishing species. Carl Linnaeus was the first to propose a classification system of organisms. His system developed into the organizational structure used in the life sciences today. Viewers also learn how new scientific names are created and how the existing system has been further refined using DNA studies.

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.
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. While navigating the dense aquatic weed forest of the pond, the Cyclops is pulled off course by a hydra. After escaping its tentacles, the crew begins to study how the hydra reproduces, captures its food, and digests its prey. One of the Micronauts takes a journey inside the hydra’s digestive system to get a first-hand account of the digestive process. Part 4 of the Microscopic Monsters 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.
Part of the "Visualizing Cell Processes" series. Includes the following modules: "The Cell Machinery," "A Variety of Cells," "Organic Molecules: The Building Blocks of Life," "Prokaryote Evolution and Diversity," and "Independently Living Eukaryotic Cells."
Discusses the terminology, processes, and products related to photosynthesis. Questions bridge segments and lead to information on tropism, seed structure, and germination. Includes a review and a quiz.
What happens when an organism can't perform aerobic cellular respiration because oxygen isn't available? Explore fermentation with Pinky and Petunia. This episode focuses on alcoholic fermentation and lactic acid fermentation. Part of "The Amoeba Sisters" series.
Discusses the diverse reproductive strategies of microorganisms. One of nine segments in a series, with all nine available on a DVD.
Many microorganisms thrive in the polluted water that is abundant with their food: bacteria and other protists. One of nine segments in a series, with all nine available on a DVD.
All living things are made from one or more cells. A cell is the simplest unit of life, and they are responsible for keeping an organism alive and functioning. In this episode, Pinky and Petunia discuss the organelles of cells. Part of "The Amoeba Sisters" series.
Characteristics enabling organisms to survive and reproduce are referred to as adaptations. This program explores the wide range of adaptations that all living things exhibit. Important terminology includes environment, characteristics, competition, survival, structural adaptations, and behavioral adaptations.
Fossils are windows to the past. This program takes a look at how fossils are formed and preserved. Special attention is given to the meaning, significance, and use of fossils in telling about past life on Earth.
This UNC TV segment explores the intricate interactions between organisms which are the building blocks of the freshwater ecosystem. These include the relationships between insects and the environment, predator and prey, water and organic waste, and nutrients and underground channels.
In this episode, Pinky and Petunia explain the organic compound ATP. It provides the energy to living organisms that drives the many processes in cells. Part of "The Amoeba Sisters" series.
Identifying the key molecular players in planarian regeneration may offer clues into how the process may work in other species, including humans. HHMI investigator Alejandro Sánchez Alvarado and postdoctoral fellow Alice Accorsi use RNA-mediated genetic interference (RNAi) to silence different genes in planaria and determine how they affect regeneration.
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to produce needed energy from nutrients. These processes help keep the Earth in balance by breaking down the food that photosynthesis produces.
Part of the "The Biology Classics" series. Paramecia are a group of unicellular ciliate protozoa. Shows how paramecia move, feed, digest, assimilate nutrients, achieve water balance, deploy defensive weapons, reproduce, and engage in the sexual exchange of genetic material. Utilizes state-of-the-art microscopy techniques to present a compelling new picture of the life of paramecia.
Explore efforts to decrease the use of pesticides by genetically engineering resistance in plants. Viewers also consider the debate over the benefits and risks of genetically modified organisms. Part of "The Botany of Desire" series.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on assigning organisms to the correct family as outlined by the scientific classification system. Part of the Science Video Vocab series.
