In this type of cell division a parent cell finally a parent cell divides in to 2 daughter cells in that way that rhe number of chromosomes in the daughter cells remains same as in parent cell mitosis is a continuous process, is karyokinesis can be divided into four phases. prophase, metaphase , anaphase and telophase.
1) "PROPHASE"
during early prophase chromatin material condenses and become visible as thick coiled hair like structures called chromosome comma each chromosome at this stage is already double, consists of two chromatids the chromatids are attached to each other at centromere the nuclear membrane gradually disappears and at the same time centrosome divide to form two centriols each move towards the opposite pole of the cell and forms the spindle fibres the centrioles are present in plant cells.
2.) METAPHASE.
during this phase each chromosome arranges itself on the equator of the spindle , each chromosome is attached to the seprate spindle fibre by its centromere
2.)ANAPHASE.
In this phase the centromere of a chromosome divide and the chromatics of each chromosome separates from each other and begin to move towards opposite poles in this way one set of the chromosomes ( its chromatid is now is an independent chromosome) move towards one pole while the other set towards the other pole
4:) TELOPHASE.
this is a stage where the chromatid (now chromosomes reach the poles) and their movement stops
, each Pole receive the same number of chromosomes are present in the parent cell the nuclear membrane is reformed around it set of chromosomes in this way two daughter nuclei are formed , in each cell .
soon the cytoplasm of the cell also divides and the two daughter cells arise. the nucleus of each daughter cell contains the same number of chromosomes as in the parent cell in this way daughter cells are exact copies of the parent cell
