Spirogyra, live, approx 80mL

AU$22.90 ex GST

Spirogyra - filamentous algae.

Phylum Chlorophyta.

Class Zygnematales.

Qty: Filamentous

Spirogyra is supplied in a 120mL vial with approximately 80mL pond water and the Spirogyra strands. Please see product photo for a guide.

Spirogyra is found in the quiet waters of ponds, ditches and lagoons, where it often forms large green masses below the surface of the water.  Occasionally it occurs at the edge of running water.

Spirogyra consists of long filaments of cells arranged end to end and containing a spiral chloroplast.  Reproduction occurs when two filaments come to lie side by side.  A tube is formed, connecting two of the cells and the protoplasm fuses, as do the nuclei of the two cells to complete fertilization.  Four haploid nuclei are produced, three of which degenerate.  After the rupture of the zygote wall, the fourth nucleus divides mitotically to form the new haploid filament.

Spirogyra is not easily cultured for prolonged periods once removed from its native environment.  It will sometimes survive in a well balanced aquarium.
