Unicellular vs. multicellular organisms and their level of organization.
Unicellular organisms are made up of a single cell, like bacteria and some protists, whereas multicellular organisms consist of multiple cells with specialized functions, forming tissues and organs, like plants and animals.
The difference lies in the level of organization within the organism; unicellular organisms function as individual cells, while multicellular organisms have a division of labor amongst their specialized cells.
For instance, in the human body, different cells form tissues like muscle tissue or nerve tissue, each carrying out specific functions that contribute to the overall survival and functioning of the organism.
