Compare the structural features and vital processes of unicellular and multicellular animals. What do they have in common? What is the difference?

Single-celled and multicellular organisms differ not only in the number of cells. Despite the fact that they have almost the same structure (nucleus, cytoplasm, cell membrane), if one cell is isolated from a multicellular organism, it will not be able to live independently. But even if you put together many unicellular organisms, they do not form a multicellular one. This is due to the fact that every single-celled organism has everything it needs to exist. It can independently absorb water and nutrients. He can break them down, receive energy and store them. In a multicellular organism, each cell performs its function, and then shares the results of its work with other cells. As a result, they work together as a single organism.
