Detailed explanation-1: -Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions. In humans, cells differentiate early in development to become nerve cells, skin cells, muscle cells, blood cells, and other types of cells.
Detailed explanation-2: -An organism which is made of more than one cell is called a multi-cellular organism. Humans, animals and plants are some multi-cellular organisms which are made of millions to trillions of cells.
Detailed explanation-3: -The organisms which are made up of more than one cell (two to billions of cells) are called multicellular organisms.
Detailed explanation-4: -Multicellular organisms are made up of multiple cells instead of one large cell. This is so because, as the cell size increases the surface area and the volume increases. But the rate of increase of cytoplasm or volume is much more than the rate of increase of surface area.
