Which of the following is correct about cell theory in view of the current extent of our knowledge regarding cell structure?
Correct answer: C. Cell theory means that all living objects consist of cells whether or not they are capable of reproducing.
- A. Modified cell theory means that all living beings are composed of cells capable of reproducing.
- B. Cell theory does not hold good because all living beings (e.g., viruses) do not have cellular organization.
- C. Cell theory means that all living objects consist of cells whether or not they are capable of reproducing.
- D. None of the above
Explanation
The correct answer is Option C. Cell theory fundamentally states that all living organisms are composed of cells, which are regarded as the basic structural and functional units of life. This remains true regardless of whether all cells have the capacity to reproduce.
