Apparently, Polysiphonia have one of the most complex life cycles of any living organism, so the author won't be brave enough to state which of the reproductive structures is shown in the image! 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.

To be able to see bacteria under a light microscope, growing the bacteria in a culture media that is rich in nutrients is often necessary. However, since different bacteria come with different nutrient requirements, it’s important to choose the right type of media based on the bacteria that is going to be cultured.

Specimens of Polysiphonia sensu lato were collected from the subtidal zone in Jeju Island and transported them to the laboratory using a container with ice. Samples were studied under the microscope (ECLIPS 80i; Nikon, Tokyo, Japan) and were made as voucher specimens.

Thallus Structure of Polysiphonia: The thallus is filamentous, red or purple red in colour. The thallus is multi-axial and all cells are connected by pit connections hence, the name given is Polysiphonia. Due to continuous branching and re-branching the thallus has feathery appearance (Fig. 1A).
