उत्तर
Centrosome
Explanation:
The cell wall, cell membrane, and large vacuole are all characteristic structures found in plant cells. The centrosome is the odd one out because it is exclusively found in animal cells, where it initiates and regulates cell division by forming spindle fibres. Plant cells lack centrosomes and instead form spindle fibres using polar caps during division.
