What is Spirogyra filament?
Spirogyra filaments are slippery and float in large masses. Spirogyra is a genus of green algae that belong to the order Zygnematales. These free-flowing, filamentous algae are characterized by ribbon-shaped chloroplasts that are arranged in a helical manner inside the cells.

Why Spirogyra is called so?
The filamentous algae genus Spirogyra owes its name to the characteristic spiral shape of the chloroplasts possessed by its members. Sometimes alternatively known as water-silk, mermaid’s tresses, or pond scum, a large presence of the unbranched algae often indicates the nutrient enrichment of freshwater bodies.
What is the shape of Ulothrix?
Note: Ulothrix is a green algae having barrel shaped or cylindrical cells. The cell wall is composed of propectin and cellulose. It lacks its mucilage. As we see the plant cell structure it bears girdle shaped chloroplast.
What type of algae is Ulothrix?
filamentous green algae
Ulothrix, genus of filamentous green algae (family Ulotrichaceae) found in marine and fresh waters. Each cell contains a distinct nucleus, a central vacuole, and a large thin chloroplast with at least one pyrenoid. The specialized cell for attachment is called the holdfast, and the filaments are typically unbranched.
What is the meaning of filamentous structure?
[fil″ah-men´tus] composed of long, threadlike structures.
Is euglena an algae?
Euglena is a genus of unicellular, freshwater organisms that are very common in ponds and small bodies of water, especially if they are rich in nutrients and consequently high in algae (aka ‘pond scum’).
What is the scientific name of algae?
The scientific study of algae is called phycology. Some references include blue-green algae.
What is the scientific name of water Silk?
Spirogyra

What is the difference between algae and spirogyra?
As nouns the difference between algae and spirogyra is that algae is (alga) while spirogyra is any of a group of freshwater, filamentous green algae, of the genus , having chloroplasts arranged in spirals.
What happens to the vegetative filament in a Spirogyra?
After fragmentation, the vegetative filament develops into a new filament where each fragment undergoes multiple division and elongation to form a new filament. When a Spirogyra filament attains considerable length, it breaks into smaller pieces that can grow into a mature organism.
What are the broken pieces of a filament called?
Hormogonia: The broken pieces of a filament are called hormogonia. Double concave discs of gelatinous material are formed between two cells. It is called separation disc. The filaments break at these points and form hormogonia. Hormospores: Under unfavourable conditions, some hormogonia develop thick wall. They are called hormospores.
What makes up the filament of a cyanobacteria?
The filament is composed of trichomes. Trichome is a chain of cell. Each filament is surrounded by mucilaginous sheath. A trichome with its enclosing sheath is called filament. Trichome may be branched or unbranched. Locomotion: They lack flagella. They use gas vesicle to move in the water.
Where is the nucleus suspended in a filament?
Each cell of the filaments features a large central vacuole, within which the nucleus is suspended by fine strands of cytoplasm. The chloroplasts form a spiral around the vacuole.
