Complex organisms need cells that perform many different functions. Complex organisms are capable of a lot of different things, and that variety needs to be supported on the cellular level. Without them, complex organisms cannot perform different functions.
Without them, complex organisms cannot perform different functions.

WITHOUT THEM< COMPLEX ORGANISMS CANNOT PERFORM DIFFERENT FUNCTIONS
One cell or unicellular organism cells are of simpler forms mostly prokaryotes. In one cell organisms all the vital functions which are necessary for the life is carried by the same cell. In many cell or multicellular organisms the cells are complex and are called eukaryotic cells. In multicellular organism the cells are divided and are specialized in performing different functions according to need as some cells like blood work to carry oxygen, some cell hv functions like secreating some fluids like hormones or vitamins.
Multicellular organisms are much more complex. The body needs to supply food and nutrients, transport materials, remove wastes, and fight infections. Specialized cells carry out different functions in order for the body to function properly.
yes they have more mass which needs more energy!
cell division is how organisms grow.
Large organisms need transport systems to supply all their cells with food, oxygen and other materials.Multi-cellular organisms are too big and not all of their cells have contact with the external environment. All organisms need to exchange substances with their environment - take in needed molecules and get rid of waste. A uni-cellular organism can use the processes of osmosis, diffusion and active transport to transport substances in and out of the organism, which is in this case just one cell. But as organisms increase in size, they need a specialized transport system to exchange substances between the internal environment and the external environment. Interestingly enough, osmosis and diffusion are still the important mechanisms at the cellular level.

true
Cell specialization is necessary to support multicellular life because multicellular organisms need different tissues. This means it needs cells to make up those tissues and perform different functions.
Specialized cells are dependent on other specialized cells because they need to live off other cells otherwise specialized cells wouldn't exist. Every specialized cell is designed to carry out a special function, there for we need a bunch of different specialized cells for the entire organism to survive.
Multicellular organisms, of course! Unicellular organisms have one cell, so no cellular specialization.
Multicellular organisms are much more complex. The body needs to supply food and nutrients, transport materials, remove wastes, and fight infections. Specialized cells carry out different functions in order for the body to function properly.

Because there is only one cell and they are not as complex as multi celled-organisms. Example: A rabbit needs to perform more functions, while a single celled organism, such as amoeba, doesn't need to perform a lot of functions. The rabbit is more complex, so it has a hierarchy of organization.
Because they don't need to. The operative term here is single celled...single celled organisms cannot survive if they specialize at the same level as a cell in a multicellular organism. Now it can breathe but it can't eat
