Type of cell division not formed spindle fibre
Explanation:
- Cells cannot divide without spindle fibre.
- Because, during Anaphase Spindle fibres get attached to the Kinetochore resulting in the pull apart of the sister chromatids of the Chromosomes followed by division of cytoplasm (Cytokinesis) and which is the most important step of cell division.
- So, if there will be no spindle fibres, means no separation of sister chromatids I.e. No division of cell.
- Actually spindle fibres are Cytoskeletons ( made up of microtubules)
- They used to stop the formation of spindle fibres only. By using drugs like Colecemids, Vinblastin, Colchichin etc they inhibits the polymerisation of microtubules I.e. Inhibits spindle fibre formation.

All somatic cells form spindle fibres.
Explanation:
- During the process of mitosis and meiosis spindle fibre is formed in the cell wall.
- This single fibre helps in the division of the cytoplasm of cytokinesis full stop if spindle fibres are not formed then the cytoplasm of the cells will not separate.
- As a result the process of cell division will go in vain full stop hens spindle fibres are formed in all types of somatic cells during mitosis or the reproductive cell during meiosis.
