spirogyra, (genus Spirogyra), any member of a genus of some 400 species of free-floating green algae (division Chlorophyta) found in freshwater environments around the world. Named for their beautiful spiral chloroplasts, spirogyras are filamentous algae that consist of thin unbranched chains of cylindrical cells.

The genus Spirogyra is abundant in freshwater habitats worldwide, and comprises approximately 380 species.

What is the order of Spirogyra?

The Zygnematales, also called the Conjugatales, are an order of green algae, comprising several thousand different species in two families.


What kingdom and domain is Spirogyra?

Spirogyra is classified under Chlorophyta due to the presence of chlorophyll.

What are the 5 characteristics of Spirogyra?

Spirogyra Characteristics

Each chloroplast houses several pyrenoids. Their bodies are characterized by multicellular filaments, which are present underneath a mucilaginous sheath. Pectin and cellulose can be found on the cell walls of such algae. Reproduction occurs asexually, sexually and vegetatively.

What is common name of Spirogyra?

Spirogyra are commonly known as “water silk or pond silk”. They have a filamentous and unbranched vegetative structure. There are around 400 species of Spirogyra found.

What level of organization is Spirogyra?

Unicellular organisms like the Amoeba, Spirogyra etc fall in the cellular level of organization.

Does Spirogyra belong to kingdom Protista?

Spirogyra is described as the filamentous green algae and belongs to the Zygnematales order. It is one of the members of the protist kingdom. The name of spirogyra is derived from the spiral or helical arrangement of its chloroplast.

Why is Spirogyra a protist?

Spirogyra are most commonly classified as belonging to the Kingdom Protists, because they have characteristics of both plants and animals.

How many species of Spirogyra have been recorded to form Aplanospores?

We induced conjugation or aplanospore formation under controlled laboratory conditions in 15 of the 52 strains, which allowed us to identify 13 species. Two of the thirteen species were assignable to a related but taxonomically uncertain genus, Temnogyra, based on the unique characteristics of sexual reproduction.

Who is known as father of algae?

Mandayam Osuri Parthasarathy Iyengar (15 December 1886–10 December 1963) was a prominent Indian botanist and phycologist who researched the structure, cytology, reproduction and taxonomy of algae. He is known as the “father of Indian phycology” or “father of algology in India”.

Is Spirogyra a plant or animal?

Solution : A spirogyra is a plant because of the presence of chlorophyll which allows it to make its own food.

What is the phylum of Spirogyra?

Charophyta is a group of freshwater green algae, called charophytes, sometimes treated as a division, yet also as a superdivision or an unranked clade.


Who first discovered algae?

Jean Pierre Étienne Vaucher (1803) was perhaps the first to propose a system of classification of algae, and he recognized three groups, Conferves, Ulves, and Tremelles.

What is green algae called?

Chlorophyta are commonly known as green algae and sometimes, loosely, as seaweed. They grow primarily in freshwater and saltwater, although some are found on land. They may be unicellular (one cell), multicellular (many cells), colonial (a loose aggregation of cells), or coenocytic (one large cell).
