Question

cells consist of many organelles, yet we do not call any of these organisms as structural and functional unit of living organisms.explain.

Answer 1

As the organelles are freely present in the cytoplasm they do not carry out functions independently but perform as a whole which is interlinked.These functions as a whole forms the functions of a cell.Hence these are not called structural and functional units.

Answer 2

Although cell organelles have specific structures and perform specific functions but they cannot be called structural and functional units of living organisms. This is so because they can perform their functions only when they are within a living cell. They cannot function outside the cell as an independent unit.
