Spindle fibers running from pole to pole are called:
Correct answer: A. Continuous spindle fibres
- A. Continuous spindle fibres
- B. Half spindle fibres
- C. Discontinuous spindle fibres
- D. Astral fibres
- E. All are incorrect
Explanation
Continuous spindle fibers are microtubules that attach to the centromeres of chromosomes. The centromere is a specialized region on a chromosome that serves as a point of attachment for spindle fibers. These microtubules exert forces on the chromosomes to move them toward the poles of the cell during anaphase. During this process, the continuous spindle fibers shorten, causing the sister chromatids to separate and move toward opposite poles.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
