  4. Membrane    

hintHint:

Species containing one nucleus are called unicellular organisms

The correct answer is: Cell



    •  Cells are the smallest structural and functional unit of life 
    • Some species contain only one nucleus and are called unicellular like bacteria
    • Some species are clustered into more than one cell and are called multicellular organisms like humans,  animals etc 
    • Cells form the tissue,  they combine to form organs , organ systems and ultimately a whole organism is formed
