Ward's® Live Diatom cultures

This species of freshwater algae is commonly used for research on photosynthesis.

Specially Prepared 'Real-Life' Combinations

Freshwater. Colonial; colonies elliptical, made up of 16–32 cells. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

Volvox globator is a species of colonial green algae that forms spherical colonies of cells.

Pink to bright rose color.
Characterized by cilia; nearly all possess two types of nuclei.

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.

Paramecium multimicronucleatumis one of the largest species of Paramecium. This ciliate contains a single macronucleus and four or more micronuclei. Grows in Dilute Alfalfa medium (Hay Medium).

One jar containing a mixture of 6 different genera of algae. Each algae is cultured individually in Ward's laboratories, and mixed together immediately prior to shipment to ensure an adequate supply of each organism.

Organisms with Characteristics of Two Kingdoms

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, Coccolithophora, Dunaliella, Ectocarpus, and Prorocentrum.

Examples of Organisms That Grow in Colonies

Ideal for comparative study, the four cultures included in this set represent green algae's variety of physical morphologies.

Bring your high school biology text to life with the algal cultures included in this set of 12 cultures commonly found in high-school textbooks.

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