During animal cell division, the spindle fibers are formed from:
Correct answer: B. Centrioles
- A. Mitochondria
- B. Centrioles
- C. Ribosomes
- D. Lysosomes
Explanation
Spindle fibers are made up of microtubules. There are two centrioles in the non-dividing stage of a cell. Each centriole has nine microtubule triplets. During the dividing stage of cell spindle fibers arise from these centrioles
