This means that various cells of multicellular organisms are differentiated to perform specific functions. Therefore, there are different types of cells in the bodies of multicellular organisms that differ from each other with respect to structure and functions. For example, the cells of root hairs in plants perform the function of absorption of water from the soil while the mesophyll cells of their leaves perform the function of photosynthesis.
