Concept:The flower is the reproductive organ of a plant.
Explanation:The diagram shows the levels of organisation in a living organism.
Levels are usually arranged from cells to tissues, then organs, and then the whole organism.
A flower is made up of different tissues working together as one unit.
This makes it an organ, specifically the reproductive organ of a flowering plant.
The part labelled as the organ level in the diagram is therefore the correct answer.
Since a flower is an organ and not a tissue or a whole organism, it belongs to that labelled part.
Answer:The flower belongs to the part labelled III.
