Multicellular organisms need specialised organ systems, whereas all the life processes in a unicellular organism take place in that one cell. Multicellular organisms need organ systems to carry out functions such as:1  Communication between cells, eg the nervous system and circulatory system.2  Supplying the cells with nutrients, eg the digestive system. 3  Controlling exchanges with the environment, eg the respiratory system and excretory system.imple organisms may be unicellular, consisting of just one cell, while more complex organisms are multicellular. There are two types of cell division. Mitosis is used for growth and repair and produces diploid cells identical to each other and the parent cell.
