. The size of the cells of an organism has no relation with the size of its body. Do you agree? Give the reason for your answer
Answer: Size of the cells of an organism has no relation with the size of its body because the cell size of a rat and cell size of an elephant will not be different in size. The cell organelles like mitochondria, Golgi complex, ribosomes, nucleus, etc., have specific functions and carry out specific functions in a cell but they cannot be called as the structural and functional units of living organisms. This is because they can function only when present inside a living cell. They cannot act as independent units. The nuclei, on the contrary, has an independent existence. It is the smallest, structural and functional unit of life.
