Bacteria are unicellular organisms, which is to say, a bacterium is a cell. Bacteria differ from the cells of multicellular organisms in that they are generally much smaller and less specialized.
They differ because multicelluar organisms live longer and are bigger
Protozoa are single-celled organisms that behave like tiny animals - hunting and gathering other microbes for food. Many protozoa call your intestinal tract home and are harmless. Others cause disease, such as: giardia, malaria. toxoplasmosis. Protozoa often spend part of their life cycle outside of humans or other hosts, living in food, soil, water or insects. Some protozoa invade your body through the food you eat or the water you drink. Others, such as malaria, are transmitted by mosquitoes.Most reproduce asexually by budding, although a few do so by mitosis. Yeasts are unicellular, although some species with yeast forms may become multicellular through the formation of a string of connected budding cells known as pseudohyphae as seen in most molds.Answers.com
Unicellular and multicellular environments may vary. Multicellular organisms are able to do more functions, and unicellular is one-cell, so their functions are limited, although some unicellular ones such as thermophiles and photosynthetic bacteria can thrive in any environment with sun or heat. Multicellular ones like animals, can be found anywhere active, although different types exist in different places.
Protozoa eat food to obtain energy and algae use photosynthesis.

Cilia and flagella are the means of locomotion in unicellular organisms. They differ in the numbers found in cell, their sizes and their shapes.
Metazoa = Multicellular, various types of cell in the body perform various tasks for the survival of the body, it lies in both vertebrate and invertebrate, they are non-microscopicProtozoa = Unicellular, the single cell perform all the tasks for it's survival, It lies only in invertebrate, they are totally microscopic (until they combine to be visible like: Fungi)
You need to explain what you mean by 'colonial'. Do you mean in the Colonial period of US history or are you referring to the diasporas of these two groups?
Unicellular organisms have to complete all tasks to survive, and obviously have no specialised cells, while a multi cellular cell would be specialised and be made for a specific task such as a lung cell.
