Classic experiment to demonstrate crossing over.

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

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

Characterized by green plastids and cell walls composed of cellulose.

Zygomycete. Dung Mold. Mating strain; cross with Mucor heimalis (-) for zygospore formation. Incubation temperature 25°C. Potato dextrose agar growth medium

This organism is an aerobic organism that is commonly found as part of normal human intestinal flora. It is pathogenic.

All microbial cultures undergo an extensive quality control program prior to releasing for sale, so they are guaranteed for purity as well as for species.

Conifers come in all shapes and sizes — and so do their cones.
Includes: 6 pine cones, 6 spruce cones and 6 cedar cones.
*Pine cone factoid: Pine cones can forecast the weather! In dry weather, the scales dry up and open out. If they start to close up, wet weather is coming!

Supplied as tube cultures. Comes with culture and handling instructions, as well as the manual Working with Fungi.

Eight strains: a1 (HAO), α1 (HBO), a2 (HAR), α2 (HBR), a3 (HAT), α3 (HBT), a4 (HART), α4 (HBRT).

Freshwater. Filamentous. True branching, dimorphic structure. Basic culture solution.

Shipped in a form that provides the best quality specimen. Most are supplied in 16 x 125 mm tubes, 2 oz. jars, or 8 oz. jars..

Aeolosoma sp. A small, freshwater Oligochaete, Aeolosoma is characterized by colorful oil droplets in its body. It’s easy to culture large quantities of this microscopic organism for use in regeneration experiments: Simply add hay and wheat grains to hay medium. Culture instructions are included. Size: 2–3 mm.

Freshwater. Filamentous. Trichomes radiating from basil heterocysts. Basic culture solution.

Shipped in a form that provides the best quality specimen. Most are supplied in 16 x 125 mm tubes, 2 oz. jars, or 8 oz. jars.

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.
