Specially Prepared 'Real-Life' Combinations

Produce a Variety of Organisms Simply by Adding Water

Observe Two Protists Hunting Included Prey

Usually found in freshwater and mosses, this organism has a hard umbrella shaped shell or "test", out of which finger-like pseudopodia project.

Four individually labeled cultures — Euglena, Amoeba, Paramecium and Stentor — give students a comparison of three phyla from the kingdom Protista. Includes materials for 30 students, background information, and a teacher’s guide with subculturing instructions.

Living Cultures Plus Comprehensive Materials for In-Depth Study.

With stiff 'arms' radiating in all directions, these microscopic organisms look like sea urchins

Cellular slime mold. Demonstrates amoeboid state, pseudoplasmodial state, and fruiting body, or sorocarp. Found in woodland soil in decomposing vegetation where bacteria are abundant. Incubation temperature 25°C. Plate cultures grown with Enterobacteria as food source; freeze-dried cultures include food source.

Characterized by an amoeboid stage (lacking cell walls) and a fungus-like reproductive structure.

Specially Prepared “Real-Life” Combinations
The world is teeming with a wide variety of microlife, making studying samples of pond water complicated especially for the beginning student. To lessen the confusion, WARD’S has prepared different culture mixes that reflect protist combinations that occur in the real world, yet eliminates the hundreds of other life-forms found in a collected sample. Comes with a dichotomous key and either the Working with Algae or the Working with Protozoa manual. Supplied in a single jar.

Contents: Amphidinium, Cyclotella and Thalassiosira.
