A quick and colorful demonstration of Mendel’s Law of Segregation.

Supplied in a jar of 50% glycerine. Enough materials for 10 students, unless specified as a jar of each.

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

Members of the Pelomyxa genus look very much like Amoeba. Pelomyxa, however, have many nuclei, whereas Amoeba have only one.

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.

Our choice of three from the following: Actinosphaerium, Amoeba, Arcella, Centropyxis, and Difflugia.

Paramecium bursaria is a ciliate that contains mutualistic algae called Zoochlorella. The algae lives in the cytoplasma of the Paramecium and provides it with food. Paramecium bursaria grows in Dilute Alfalfa Medium (Hay Medium) or Soil Water Medium. Requires light for growth.

Examples of Organisms That Grow in Colonies

Examples of eight different types of algae, grouped by the color of their plastids.

Paramecium aurelia is the smallest species of Paramecium we offer. Paramecium aurelia is characterized by cilia, which it uses for locomotion and feeing. Contains a macronucleus and two micronuclei. Grows in Dilute Alfalfa Medium (Hay Medium).

Hypsibius sp. The water bear is a complex animal representing the unusual phylum of Tardigrades, which contains about 400 marine, terrestrial, and freshwater species.

The marine hermit crab is a scavenger and preys on small animals.
