How does mitosis occur in plants without centrioles and centrosomes. We are taught that spindle fibres are formed by centrioles moving to opposite poles of the cell and plant cells don't posses centrioles. Then how is the spindle apparatus is formed and constricted to divide the chromatids.

Solution

Spindle fibres are not fromed from the centrioles in plant cells.There are different mecahnisms by which spindles can be formed. In animal cells majorly it is with the help of centrioles. There are other structures like,chromatin,kinetochore ,cell wall components are all involved in the formation of spindle apparatus.So all these mecahnisms coordindate to form spindle apparatus in animal and plant cells.In plants as centrioles are not there other mechanisms are utilised in spindle formation.
