Answer:all life form contains more than one cell
Explanation: thats the only question that's not true
Historically, many ideas concerning cells have been examined, leaving three to be incorporated into the cell theory except that all life forms are made up of more than one cell as the life forms can either be single or multicellular.
What is the significance of the theory behind the cell?Cell theory, a foundational concept in biology, states that all living organisms are made of cells, and these cells come from pre-existing cells and not from anywhere else. All these postulates support the idea that cells are the basic building blocks of life and that life can only be generated through the replication process.
Hence, historically, many ideas concerning cells have been examined, leaving three to be incorporated into the cell theory except that all life forms are made up of more than one cell as the life forms can either be single or multicellular.
