Question
Cells consist of many organelles, yet we do not call any of these organelles as structural and functional unit of living organisms. Explain.
Solution
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 CEI, on the contrary has independent existence. It is the smallest, structural and functional unit of life.
