A multicellular organism is made up of millions of cells, all of which carry out specific and different functions depending on their shapes and structures, and the organelles contained in them.
In multicellular organisms, cells make up tissues, tissues make up organs and organs make up systems.
In an entity, they cooperate with one another and ensure the organism carry out its seven main living processes.
The kind of organisation is extremely necessary to allow different systems to carry out specific functions and to enable the organism to be a complete and functional individual.
