Is the following statement correct? If it is wrong, correct the statement. “Unicellular organisms do not respire, only multicellular organisms respire”

The above mentioned statement is wrong. The unicellular organisms also respire, reproduce and carry all metabolic functions like multicellular organisms. The difference is that all the functions are performed by the single cell in a unicellular organism. Similar functions in multicellular organisms are performed by various organs (organ system) which are made up of many different types of cells.
