The cells of multicellular organisms become specialized for particular tasks and communicate with one another to maintain homeostasis. Specialized cells in multicellular organisms are organized into groups. A tissue is a group of similar cells that performs a particular function.

they help avoid mistakes they give descriptive information about the species allow organisms to be organized easily and efficiently organisms with similar evolutionary history are classified together
Unicellular organisms are the organisms which have only on cell as the body eg: Amoeba, This is a unicellular organism which can perform all functions just like a multicellular animal. It performs respiration without any organs just like a multicelluar animal which has respiratory organs(Gills, lungs etc). and also reproduction, excretion, circulation, etc. A multicellular animal has many cells(Millions, trillions of cells) these cells are grouped to form tissues which perform a similar function (ie all the cells in a tissue perform similar function) The tissues are organized to form organs (Liver, Pancreas, Muscles etc). There are many differences between a unicellular organisms and multicellular organisms.
Bodies of multicellular organisms, particularly animals, are organized on the basis of tissues, organ and organ systems. A tissue is composed of cells with similar structures and functions. An organ is composed of several tissues grouped together into a structural and functional unit. And an organ system is a group of organs that work together in the performance of a specific function.
Cells that perform similar functions make tissues, yes. Cooperating tissues make organs, which ,by cooperating, make organ systems, which, therefore, create organisms.

cell membrane
Protists can be unicellular or in a colony of similar organisms but do not differentiate into tissues. They are eukaryotes.
taxonomy
That just means how it is labelled. Organisms are organized with labels and names based on the other organisms is it similar to.
