Detailed explanation-1: -The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms.
Detailed explanation-2: -Scientists once thought that life spontaneously arose from nonliving things. Thanks to experimentation and the invention of the microscope, it is now known that life comes from preexisting life and that cells come from preexisting cells.
Detailed explanation-3: -No. The cell theory states that all cells arise from existing cells. This does not mean that all cells necessarily reproduce. However, students may infer that all cells contain DNA and have the ability to reproduce.
Detailed explanation-4: -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-5: -Detailed Solution. The correct answer is All cells are identical.
