Is it true that all living things are made up of one or more cells?

Answer 1

All the major kingdoms are multicellular (plants, animals, some fungi) or unicellular (protists, bacteria, archaea, other fungi).

These things are universally agreed to be alive, however there is no definite definition of life nor is there agreement about the line between life and chemistry. Viruses which many would consider to be alive cannot be considered cells because being a simple protein coat surrounding genetic material they lack many of the distinctive characteristics of all other cells, most notably the lipid membrane that separates the cell from its surroundings. Prions take this one step further and are infectious disease causing agents that exist solely as malignant proteins, as such many consider prions to be on the edge of life and chemistry.

So if you consider viruses and/or prions to be alive then the answer is no, if you do not then the answer is yes.

Answer 2

All living things are composed of cells; but only microorganisms such as bacteria, paramecia and algae are unicellular (composed of just one cell).

Answer 3

yes, all living things are made up of 1 or more cells.

cells are the basic units of life

Answer 4

Yes all living things are made of cells some organisms have only one those are called
