if there are no centrioles in the ova, how are the spindle fibers formed?

Expert Answer:

The cellular spindle apparatus includes the spindle microtubules, associated proteins and any centrosomes or asters present at the spindle poles. Centrioles act as MTOC (Microtubule Organizing Centre) in animals. Here, the spindle fibres which are microtubular in nature are organized. Presence of MTOC in ovum assists in spindle fibre formation. Centrioles are efficient for spindle formation but are not necessarily essential.
