Unicellular cells must carry out all functions of life. Thus, the correct option is A.
Unicellular cells may be defined as those organisms that generally consist of only a single cell. This single cell carries all the essential functions of life which are required in order to survive in nature.
The complexity of the genome in a such single-celled organism is very simple. The mechanism of compartmentalization is not found inside the cell of such organisms. All the functions are carried out by the same cell.
Examples of unicellular organisms are Bacteria, amoeba, Paramecium, archaea, protozoa, unicellular algae, and unicellular fungi. They possess a cell wall made up of peptidoglycan, chitin, or other forms of polysaccharides. This protect the inner content of the cell.
Therefore, unicellular cells must carry out all functions of life. Thus, the correct option is A.
