The cell wall polysaccharides of some red algae are the source of: 1. a sugar substitute 2. a source of salt 3. glucose for the study of photosynthesis

Cell Structure of Polysiphonia: The cells have thick wall, differentiated into outer pectic and inner cellulosic layers. The cells are uninucleate with many discoid chromatophores without pyrenoids. Neighbouring cells are connected by pit connections. The cells contain large central vacuole. Reserve food is floridean starch.

They may retain both their Additionally, many cells have a single flagellum that can be used for locomotion. stimulated overgrowth by red algae such as certain species of Polysiphonia. Size is also limited by means of locomotion; Many protists are propelled by cilia Greek rhodos = red - Polysiphonia, Nemalion; Mostly marine, closely related to entire cell content functions as gamete. Polysiphonia also produces non- flagellated spermatia.

Chloroplasts evolved following an endosymbiotic event between an ancestral, photosynthetic cyanobacterium and an early eukaryotic phagotroph. This event (termed primary endosymbiosis) resulted in the origin of the red and green algae, and the glaucophytes, which make up the oldest evolutionary lineages of photosynthetic eukaryotes.

There are two types of flagella namely whiplash (Acronematic) and tinsel (pantonematic). Red -algae (Rhodophyta) lack flagella. Pyrenoid In each chloroplast one or few spherical bodies called pyrenoids are present. They are the centres of starch formation.
