Which is correct about cell theory in view of current status of our knowledge about cell structure?
It needs modification due to discovery of sub cellular structures like chloroplasts and mitochondria.
Modified cell theory means that all living beings are composed of cells capable of reproducing .
Cell theory does not hold good because all living being do not have cellular organization ( eg , viruses ).
Cell theory means that all living objects consist of cells whether or not capable of reproducing.
