Q- Do you agree that “a cell is building unit of an organism”. If yes, explain why?
Answer:- in an unicellular organism cell is capable to perform all the functions of life but in multicellular organism there is proper organization of every organs to perform a specific functions in which specific cells get collected to form tissue and many tissues are organized to form an organ and multiple organs are organized to form a organ system and many organ systems are organized to form an organism.
Therefore cell is the building unit of an organism.
Cell < tissue < organ < organ system < organism.
