Answer is not exactly known, as origin of first unicellular organisms is unknown. First multicellular organisms appeared in late Precambrian. Look up Burgess Shale for details.
Ascomycetes and Basidiomycetes are not. Filamentous chytrids and zygomycetes can be considered unicellular if there are no septa in their hyphae. For the most part, threadlike fungi are considered multicellular.
unicellular, however sometimes they are associated in groups or long strings.
The flatworm is one portion of the phylum Platyhelminthes. "Platy" meaning flat, and "helminthes" translating to worm. All species belonging to the Platyhelminthes phylum have two cell layers because their bodies consist of an outer skin and also an incomplete gastrovascular system. Therefore, all flatworms are multicellular.
yes protist do have only one cell it has been known for a very long time
Unicellular: Algae like Chlorella are single-celled organisms. Colonial: Algae such as Volvox form colonies of cells. Filamentous: Algae like Spirogyra form long chains of cells. Thalloid: Algae such as kelp have a plant-like body structure with differentiated tissues.
No, spirogyra is not a single-celled organism. It is a type of multicellular green algae that forms long, filamentous structures composed of chains of cells. Each cell within the filament contains a single nucleus.
A unicellular organism and a multicellular organism are different because, those that are unicellular consist of only a single cell. Those cells are very simple because they lack a nuclei and their DNA is not separated from the rest of the cell . Any injury or death of cell in unicellular organism leads to death's. life span is short and theirs cell is comparatively large.Multicellular organisms on the other hand, are made of many cells and are major complex. Their cells do have a nuclei and have their DNA separated from the rest of the cell.Theirs life span is long. They have better adaptability for survival.theirs cell size is smaller .

Oscillatoria is multicellular, forming long filamentous structures made up of individual cells. Each cell is linked in a chain-like fashion, creating the characteristic appearance of Oscillatoria colonies.
Answer 1Unicellular organism evolved first.Answer 2Both unicellular and unicellular organisms had been created in the meantime by God on the creation of earth. These organisms; by God will; had been evolved to be adapted to nature.
they have lived for up to millions of years
Can be both. There are plenty of unicellular algae, such as Euglena, but most plants you see underwater are algae too (as long as they don't have flowers; a water lily is not an alga), and these are obviously multicellular. :P Oh, by the way, the singular is alga. One alga, two algae. ^^

Spirogyra is a type of colonial green algae. They are unicellular and arrange themselves in long filaments.
