Unicellular organisms:

1. Life on earth evolved from a single cell millions of years ago.
2. These single cells are known as unicellular organisms.
3. All the life processes in a unicellular organism, including digestion, excretion, and respiration, occur within a single cell.
4. So, there is no division of labour in unicellular organisms.
