Answer 2

The right sequence of the stages of organizations is -

Cell => Tissue => Organ => Organ System => Organism.

Explaination :

We know that cell is very important part or unit of the system of our body as it has both the roles of supporting and functioning of our body system.

When same type of cells comes together, they form an aggregate which is called tissue.

Similarly, when same kind of tissues forms an aggregation, organ is formed. Similarly, the system of organ is formed.

When the organ system develops completely, we can then call the individual as an organism.
