Homologous chromosomes pair up. This process is called synapsis. Each pair is called bivalent. Chromosomes line up around the equator of the spindle, attached by their centromeres to the spindle fibres, which are microtubules. The microtubules forming spindles can be of two types, i.e., kinetochore-microtubule and non-kinetochore microtubule.
Axoneme is the central core of a cilium of flagellum consisting of a central pair of filaments surrounded by nine other pairs. The equatorial plate is the plane located midway between the poles of a dividing cell during the metaphase stage of mitosis or meiosis. It is formed from the migration of the chromosome to the centre of the spindle.
