The term "protist" covers a wide range of microscopic organisms formerly clumped into "Kingdom Protista." New molecular analyses show that the protistan lines of evolution go so far back in time they can be considered as different kingdoms of life. Through stunning photography of living protists, students are introduced to amoebas, flagellates, algae, and the elegant ciliated protists in ten learning modules.

Additional information

The term "protist" covers a wide range of microscopic organisms formerly clumped into "Kingdom Protista." New molecular analyses show that the protistan lines of evolution go so far back in time they can be considered as different kingdoms of life. Through stunning photography of living protists, students are introduced to amoebas, flagellates, algae, and the elegant ciliated protists in ten learning modules. This DVD also provides 22 minutes of additional observations allowing detailed observation of these fascinating single cell life-forms.

Customer Reviews:

"Previously, whenever surfing during a red tide, I've vaguely wondered what the heck I was actually floating in: now, thanks to 'The Biology of Algae,' I know with absolute certainty that I was amongst the dinoflagellates, which are more closely related to ciliated protists than to other forms of algae (a catchall term for various photosynthetic organisms). ...In addition to dinoflagellates, the program looks at the other evolutionary branches of algae, including red, green, brown, and euglendids-using both stock footage and excellent microscopic photography-while specific examples such as Spyrogyra (not the jazz band) or Euglena help pinpoint identifying characteristics. The DVD version also includes a study guide in DVD-ROM accessible PDF format. Recommended" *** of **** Recommended E. Gieschen January/February 2005 (Volume 20, Issue 1), Video Librarian


Conveniently split into nine modules, Branches on the Tree of Life: Protists is a 45-minute DVD that describes how this group of single-celled eukaryotes is actually derived from diverse phylogentic branches and is currently undergoing reclassification. The film opens with a definition of protist and is accompanied throughout by superbly photographed live organisms viewed under a light microscope. The narrator explains that an explosion in genetic information about protists has led to the requirement that they be reclassified. Eight more modules, each of which describes a single family of protists and the criteria used for defining that family, follow the introduction. The film assumes some knowledge of biology: The viewer must be familiar with such terms as chloroplast, zygote, flagella, and microtubule. Thus, the program is most suitable for college-level students or teachers. However, it lacks enough detail to accompany more specialized undergraduate classes such as field biology or ecology. One of the high points of the film is that it shows how specimens desired for microscopic examination may be collect from a pond or stream and kept in the classroom. The program is an excellent, quick reference guide to the identification of such specimens. A nice, additional feature at the end of the film is 22 minutes of footage without narration, for students who don't have access to a pond or a microscope to practice identification of the protists.

'The Biology of Protists is a 20-minute program with interesting footage of live cellular organisms in beautiful visual detail. The organisms are shown in their natural habitats and are not from laboratory-grown cultures. The narrator describes these eukaryotic and prokaryotic life-forms to a high degree of accuracy. The information emphasizes especially the type of movement the protists exhibit in their aquatic environments. There is much discussion of evolutionary links to other protists and to higher complex life-forms with respect to conjugation, the sexual reproduction of cells, and photosynthesis. The information presented in this program is excellent for seventh- and eighth-grade cell biology curriculums. The video can be viewed in the classroom, allowing time for discussion of euglenoids, diatoms, heliozoans, amoebae and paramecia after the class has viewed films on those organisms.

"...Every organism shown in the video came from bird baths, local ponds, roadside ditches, or horse troughs. For classroom laboratories, protists collected from any of these habitats will thrive in jars of water if kept at room temperature and out of direct sunlight. The color photography of living organisms is superb and augments the narration. Music and sound effects are pleasant and add to the overall viewing experience. The video is designed for each module to be viewed independently, stopping for discussion, and then resuming the viewing to summarize the content. Laboratory observations of organisms such as parameciums and volvox will reinforce concepts outlined in the video." "...The Biology of...series is a high quality product that supports classroom instruction with the concise, understandable facts enhanced by the visual images and graphics that support the concepts outlined in each section. This program would be suitable for junior and senior high schools, as well as beginning level college
