Domain And Kingdom Of Volvox
Generally people define what constitutes the plants animals and fungi and then the protists are all the eukaryotes that are left o.
Domain and kingdom of volvox. Volvox thrives in the form of colonies and each colony contains about 500 to 50 000 algal cells. The vegetative structure or plant body of spirogyra is known as thallus. Volvox is a common freshwater free floating chlorophytic green alga that belongs to volvocaceae family under order volvocales of division chlorophyta. Volvox form spherical or oval hollow colonies that contain some 500 to 60 000 cells embedded in a gelatinous wall and that are often just visible with the naked eye.
This surface contains an extracellular matrix which is made up of glycoproteins. These colonies are embedded in a hollow spherical surface which is known as coenobium.

Volvox is a polyphyletic genus in the volvocine green algae clade.
Numerous flagellate somatic cells and a smaller number of germ cells lacking in soma that are embedded in the surface of a hollow sphere or coenobium containing an extracellular matrix made of glycoproteins.

Volvox carteri is a motile multicellular eukaryotic species of green alga comprised of about 2 000 small somatic cells and 16 large reproductive cells also known as gonidia which interact in an extracellular matrix to form hollow spherical colonies. Volvox commonly known as green algae is a group of freshwater free floating organisms divided into about twenty species they are primitive multi celled organisms belonging to the plant kingdom forming a direct link between the lower single celled organisms and the higher complex organisms.
Under a light microscope spirogyra is seen as long threadlike green colonies called filaments that are joined end to end without any differentiation into base and apex. What is the domain of volvox. I am sorry to be vague but the answer is yes the definition of the kingdoms varies from one author to another. Each mature volvox colony is composed of up to thousands of cells from two differentiated cell types.
They occur in temporary and permanent freshwater tanks ponds pools ditches etc. The thallus is un branched and filamentous shaped measuring approximately 10 to 100 μm in width and may grow up to several centimeters in length. Volvox genus of some 20 species of freshwater green algae division chlorophyta found worldwide.
