Which statements accurately describe cells? Check all that apply.

The following statements accurately describe cells:

1. All organisms are made up of cells.
2. Cells are the smallest unit of life.
3. Both unicellular and multicellular organisms are made up of cells.

The statements "Cells only make up unicellular organisms" and "A mouse is a unicellular organism made up of one cell" are inaccurate. Cells can make up multicellular organisms, and a mouse is a multicellular organism, not unicellular.
