Bulbochaete (Knoll bristles algae) is an algae - genus from the class of Chlorophyceae . It wasdescribedby Carl Adolph Agardh in 1817.

description

Bulbochaete forms branched, single-row, upright filaments with cylindrical, sometimes barrel-shaped cells . In the cells there is a nucleus in the middle of the cell, and a cylindrical, reticulate chloroplast with pyrenoids . Characteristic of Bulbochaete are long, thin, colorless hair cells with an onion-shaped thickened base, which stand in twos at the end of each branch, at the end of the thread. Growth occurs through cell division at the base of the filament and side branches.

Reproduction

The asexual reproduction is effected by the formation of a large stephanokonten zoospore that passes through a pore into the open in a sporangium.

The sexual reproduction is carried out by egg fertilization ( oogamy ); individual cells at the end of short side branches each form a short oogonium (egg container). In special short cells, stephanokont cells are formed and released, which germinate near the oogonium, or directly fertilize the egg cell as male sex cells.

distribution

Bulbochaete lives on solid substrate, on thread algae and aquatic plants in nutrient-poor, often boggy, stagnant waters.
