✔️No, these levels are not present in unicellular organisms because unicellular organism consists of single cell.

Answer 2

The lower level in the multicellular organisms are :

(1) Cells.

(2) Tissues.

(3) Organs.

Among these three, the lowest level is the cell. Then comes the tissue. When the cells having similar type of characters or features forms an aggregation, then formation of tissues occurs.
