What features of the cell structure can ensure the performance of functions inherent in the whole organism?

This mainly concerns the cells of unicellular organisms, and not a specific cell of a multicellular one. There are various structures inside the cell – organelles. This is an analogue of the organs of the whole organism. Certain organelles perform their functions. These are storage of genetic information, digestion, energy production, cell protection, protein synthesis, storage of organic matter and many other functions. Multicellular cells are often dependent on other cells as a system. The unicellular organisms are independent.
