how are cells similar in multicellular organism
Unicellular organisms are made up of only one cell, while some multicellular organisms are comprised of trillions of cells. In multicellular organisms, groups of cells sharing similar structure form tissues that carry out a specialized function.Different tissue layers form organs.lthough multicellular organisms can have diverse cell types, all cells have certain parts in common (see the interactive cell picture below). All cells are bound by a cell membrane and contain cytoplasm, which is where the cell parts lie.
