Detailed explanation-1: -Multicellular organisms are made of more than one cell and are complex organisms. They are visible to the naked eye. They possess distinct organs and organ systems. They are eukaryotes, i.e., they contain membrane-bound structures.

Detailed explanation-2: -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-3: -multicellular organism, an organism composed of many cells, which are to varying degrees integrated and independent.

Detailed explanation-4: -What is one reason multicellular organisms, such as people, are made up of many small cells instead of one large cell? Smaller cells have more surface area for oxygen and nutrients to diffuse into the cytoplasm.
