How does the spindle fibre form in a plant?

Unlike the animal cells the plant cells lack the “centrioles” which help in the formation of spindle apparatus. Plant cells contain a special tubulin (protein) celled as “Gamma tubulin” which is used to nucleate microtubules just like centrioles in animal cells . read more

Spindle fibers form in plant cells without centrioles by the centromere. They are responsible in organizing the spindle especially for plants which lacks centrioles. Centromere is the strongest and the thinnest region of a chromosome. read more

Thespindle fibres are formed by the centrosomes not the cenrioles.The centrioles come to the MTCs ( micro tubules organising centers) which are present in the centrosomes which make up the spindle fibers on which the chromosomes are held. read more
