no...bird's are not single celled
A single celled animal is an animal that only has one cell, Eg: amoeba, Paramecium, Euglena, Chlamydomonas. Single celled animals have one cell that does all of its life processes, such as ingestion, movement, excretion, reproduction. A multi-celled animal is an animal that has many cells that each perform a specific function of life. These animals have a group of cells that digest, another group reporduces, another group controls movement, etc. If you look in the Wikipedia, it offers good information as well. Hope this helps :-)
Most protista are unicellular, but not all are. Google Chlorophyta and Rhodophyta for examples of multicelled protista.
They are all multicellular and heterotrophic, but do not have cell walls.
Organ, since it is composed if cells, tissues, molecule, and multi-celled organisms. Multi-celled organisms are only composed of one then one cell.
the cell is a cell and an animal cell is an animal cell
