Question

extension of centriole during cell division

Answer 1

At the beginning of nuclear division, two wheel-shaped protein structures called centrioles position themselves at opposite ends of the cell forming cell poles. Long protein fibers called microtubules extend from the centrioles in all possible directions, forming what is called a spindle.

Answer 2

ANSWER:

The extensions of centriole during cell division are called spindles. During cell division, protein fibres extend from the centriole in all directions which are possible.

EXPLANATION:

These long protein fibres extending from the centriole are called micro-tubules. The extensions take place in all directions. At the beginning of the cell division, two large protein-shaped structures which are called 'centrioles' are present on 'opposite ends of the cell'. During cell division, each centriole produces extensions.
