energy
One-celled organisms are their own thing. They, by themselves, take in energy, maintain homeostasis, and carry out other essential life processes.

Those cells that make up organs can't survive alone; they need the support of other cells, organs, and organ systems to survive.

Examples of these cells include: Cells in muscle tissue Brain cells Cells in the heart Cells in the lining of the small intestineThese cells require more respiration in order to produce the energy they need to perform their intended functions.
Tissue specialization has an advantage for multicellular organisms because it can make organs or organ systems. Have cells that can specialize means the cells can cooperate to form these organs.
Their cells are too close to the animal's exterior surface.
