. New cells generate from (a) bacterial fermentation (b) regeneration of old cells (c) pre-existing cells (d) abiotic materials
Option (c) is Correct The cell theory states that all the cells originate from the pre-existing cells. In cell division, the parent cells get divided into the daughter cell. The parent cells are the pre-existing cells and the daughter cells are the new cells produced from it. Option (a) is Incorrect Bacterial fermentation takes place in bacteria. The above stated 'option a' is incorrect because bacterial fermentation takes place under the anaerobic condition to produce the energy required for cell growth. Option (b) is Incorrect The cells grow to perform a function at last it mature and die. The above stated 'option b' is an incorrect option because the old cells are programmed to cell death, i.e. apoptosis and necrosis. Option (d) is Incorrect The abiotic materials are non-living factors such as temperature, moisture, and so on. The above stated 'option d' is an incorrect option because the cells are the living components which cannot be synthesized from nonliving components or abiotic components. Final Answer Option (c) pre-existing cells is Correct
