“Cart wheel” structure is exhibited by –
(1) Ribosome (2) Lysosome
(3) Centriole (4) Nucleolus
The correct answer is:
(3) Centriole
The “cartwheel” structure is characteristic of a centriole, which is a cylindrical organelle found in most eukaryotic cells. In cross-section, the centriole exhibits a cartwheel-like arrangement of microtubules, with nine triplets of microtubules arranged around a central hub.
