What order is green algae in?
In the Chlorophyceae, all freshwater flagellate green algae (as far as their phylogenetic positions are known) are members of the order Volvocales (also called Chlamydomonadales; e.g., Pröschold and Leliaert, 2007; Nakada et al., 2008a).
What is structure of Spirogyra?
The vegetative structure of Spirogyra is an unbranched filamentous thallus. The thallus is multicellular with each cylindrical cell joined end to end. They are 10-100 µm in width and may grow several centimetres in length. They are present as a slimy mass due to the presence of mucilage sheath around the filament.
How many species of Spirogyra are there?
380 species
The genus Spirogyra is abundant in freshwater habitats worldwide, and comprises approximately 380 species.

What is the life cycle of Spirogyra?
The life cycle of Spirogyra occurs via one of the three ways; vegetative, asexual, and sexual. The vegetative and sexual cycles are more common than asexual cycles. A form of alternation of generation characterizes the life cycle of Spirogyra.
What is the difference between mucor and Spirogyra?
Spirogyra contains a cell wall, nucleus, pyrenoid, and spiral chloroplasts. The Mucor spores or sporangiospores can be simple or branched, and form a spherical sporangium at the top, which is supported and elevated by columnar columns.

Each cell usually has two flagella that propel it through substances such as water. Volvox may be classified as a green alga in the division Chlorophyta or as a flagellated protozoan in the order Volvocales.
What is the order of algae?
Agardh (1849–1898) divided algae into six orders: Diatomaceae, Nostochineae, Confervoideae, Ulvaceae, Floriadeae and Fucoideae. Around 1880, algae along with fungi were grouped under Thallophyta, a division created by Eichler (1836).
What are the characteristics of Spirogyra?
They have a multi-cellular filamentous body with a mucilaginous sheath.

Is the Spirogyra harmful to humans?
The algae are harmful to humans in several ways. Volvocales, Chlorococcales, Myxophyceae and several others occur in such a great abundance in water, that they colour the whole water either green or blue green and cause the death of fishes.
