Multicellular
Step-by-step explanation:
- Cells are considered the fundamental units of life
- All living organisms are made up of one or more cells
- Unicellular organisms, like amoebas, consist of only a single cell
- Multicellular organisms, like people, are made up of many cells
- The cells in complex multicellular organisms like people are organized into tissues, groups of similar cells that work together on a specific task
- Organs are structures made up of two or more tissues organized to carry out a particular function, and groups of organs with related functions make up the different organ systems
Hence the benefit of multicellular organisms that is not shared by single-celled organisms is populations of cells in a multicellular body can be specialized for specific functions
