Are mosses unicellular colonial or multicellular?
There are more than 30000 species of algae and more than 12000 species of mosses. The science, which studies algae, is called algology; the science, which studies mosses, is called bryology. Algae include unicellular, multicellular and colonial organisms, while all mosses are multicellular.

Unicellular algae are plant-like autotrophs and contain chlorophyll. They include groups that have both multicellular and unicellular species: Euglenophyta, flagellated, mostly unicellular algae that occur often in fresh water. Diatoms, unicellular algae that have siliceous cell walls.
Is blood unicellular or multicellular?

Is bacteria multicellular or unicellular?
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.
Are bacteria multicellular?
Highlights. Many bacteria have a multicellular phase of their lifecycle, which fall into three broad categories based on shape and mechanism of formation. A number of pressures may have selected for multicellularity, including physicochemical stress, nutrient scarcity, predation, and environmental variability.
What are the examples of multicellular microorganisms?
Examples of multicellular organisms are (1) Algae, Bacteria (2) Bacteria, Fungi (3) Bacteria, Viruses (4) Algae, Fungi. Multicellular organisms are those that are made up of millions of cells. Algae – Photosynthetic multicellular organisms. Fungi – Multicellular nonphotosynthetic organisms.
Which is the best example of multicellular organism?

Is viruses are multicellular organisms?
Viruses are not classified as cells and therefore are neither unicellular nor multicellular organisms. Most people do not even classify viruses as “living” as they lack a metabolic system and are dependent on the host cells that they infect to reproduce.
