Detailed explanation-1: -It also states that all cells arise from pre-existing cells by cell division and do not originate spontaneously. Bacteria and other organisms therefore cannot arise spontaneously. So, the correct answer is ‘It states that bacteria and other small organisms can arise spontaneously’.
Detailed explanation-2: -Detailed Solution. The correct answer is All cells are identical.
Detailed explanation-3: -it is accepted that cells contain DNA in chromosomes and RNA in the nucleus and cytoplasm, but only in the modern cell theory. the classical cell theory does not include this. but using either classical or modern theory, it is false that all cells have DNA surrounded by a nucleus.
Detailed explanation-4: -Cell theory has 3 basic points: All living things are made of one or more cells. The cell is the smallest living thing that can perform all the functions of life. All cells must come from pre-existing cells through cellular division. Was this answer helpful?
Detailed explanation-5: -Viruses lack the typical structure of a cell and donot perform any functions of a cell hence cell theory is not applicable to viruses.
