Which answer below best explains if an organism can survive as a single cell?
An organism can survive as a single cell as long as the organism can perform all functions needed for life within that cell.
An organism cannot survive as a single cell because organisms must have many cells to perform all functions needed for life.
An organism cannot survive as a single cell because organisms cannot complete all life functions in a small space.
An organism can survive as a single cell as long as the organism has multiple structures to perform the same function.
