UNICELLULAR AND MULTICELULAR ORGANISMS

UNICELLULAR ORGANISMS
Living things that are composed of a single cell are called unicellular organisms.Their single cell performs all the funtions needed to live.






  MULTICELLULAR ORGANISMS 
Living things that are composed of two or more cells   are called
multicellular organisms. In these living things all the cells are arranged so that the organism can  perform the vital funtions.

In mullticellular organisms, cells are grouped to form different levels of organisation. The end result is  an organism
