Each of the peripheral fibril is a triplet.The adjacent triplets are also linked. The central part of the proximal region of the centriole is also proteinaceous and called the hub, which is connected with tubules of the peripheral triplets by radial spokes made of protein. The centrioles form the basal body of cilia or flagella, and spindle fibres that give rise to spindle apparatus during cell division in animal cells.
Which set of statements correctly integrates cytoskeleton, centrioles, and cilia/flagella with cell division? 1. Cytoskeleton provides mechanical support and motility in both plant and animal cells. 2. Centrioles are absent in higher plants but form basal bodies of cilia/flagella in animals. 3. Cilia/flagella possess a 9+2 axoneme structure, linked to centrioles. 4. Spindle apparatus in animal cell division originates from centrioles, while plants use other microtubule organising centres.
