CELL ULTRASTRUCTURE CELL ULTRASTRUCTURE Cells are the smallest functional units of the body‚ (Waugh‚ A. and Grant‚ A.2010). Most cells are microscopic. The largest cell in the body is the female ovum. The erythrocyte is the smallest cell. The longest cell is the neuron. Cells group together to form tissues‚ each of which has specialised function. Different tissues group together to form organs. Organs are group together to form organ systems‚ each of which performs a particular function that
