Answer:
The cell is known as the structural and functional unit of life because all living beings are formed of cells. Cells are very important for performing various life processes which are required for sustaining life on earth. Moreover, cells give form and structure, process nutrients and make it into usable energy.The nucleus lies at the periphery of cytoplasm and vacuole is located in the centre.
