"Freeze-Dried Specimens"

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.

Lives in intestine of host — mealworms — as symbiotic organism. Culture of mealworms provided.

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).

Specially Prepares "Real-Life" Combinations

One Culture from Each of the Four Major Types

Freshwater. Colonial; net-like structure with multinucleated cells. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

Freshwater. Unicellular; triangular desmid. Basic culture solution. Characterized by green plastids and cell walls composed of cellulose.

Freshwater. Unicellular; heart-shaped cell. Soil-water medium.

Characterized by a lack of rigid cellulosic walls, instead these organisms have pellicles made of protein. They store paramylon instead of starch.

Marine. Unicellular; contains same pigments as other Golden Algae but contains haptonema, unique to Haptophyceae. Coccoid, from coccoliths. Marine medium. Characterized by golden yellow plastids.

Axenic culture. Food organism. Tetrahymena medium.

Characterized by cilia; nearly all possess two types of nuclei.

Demonstrates isogamous reproduction where gametes are similar in appearance and behavior. The included copymaster details asexual and sexual versions of the life cycle. Cultures include Chlamydomonas reinhardtii(+) and (-).
