Polysiphonia, a common genus of marine red algae, is red in color because of the pigment phycobilin, which masks the green color of the chlorophyll responsible for photosynthesis. As a red-colored plant, Polysiphonia is well suited to absorb the green and blue-green light that typically penetrates the deeper seawater where these red algae thrive.

Animal Locomotion. Humans are limited to terrestrial locomotion on two limbs or swimming with all four limbs. Other animals explore both the aquatic and aerial realm more extensively. For example, birds are excellent swimmers and fliers. However, some birds are not good at moving in both air and water.

Polysiphonia is a heterotrichous alga having an erect series of branches and a filamentous prostrate section attached to the substratum by means of unicellular rhizoids. The ends of the rhizoids are flattened into lobed discs called haptera, which assist the penetration of the host tissue ( Polysiphonia parasitic form) or confirm attachment to substrata.

Polysiphonia is a genus of filamentous red algae with about 19 species on the coasts of the British Isles and about 200 species worldwide, including Crete in Greece, Antarctica and Greenland. [3] [4] Its members are known by a number of common names.

Anabaena is a cyanobacteria and does not reproduce sexually. Spirogyra produces non-flagellated male gamete during conjugation, where entire cell content functions as gamete. Polysiphonia also produces non- flagellated spermatia. The cell wall polysaccharides of some red algae are the source of: 1.
