Question

How would you know whether an organism is unicellular or multicellular

Answer 1

You would know whether an organism is unicellular or multicellular ,becuase single celled organisms are unicellular because uni means one,and organisms that have a lot of cells are multicellular  multi means many.

Answer 2

Multicellular organisms can be much larger and more complex. This is because the cells of the organism have specialised into many different types of cells such as nerve cells, blood cells, muscle cells all performing different functions.
