Introduction: It is the process by which a mature cell divides and forms two nearly equal daughter cells which resemble the parental cell in a number of characters.
Discovery: Prevost and Dumas (1824) first to study cell division during the cleavage of zygote of frog.
Nagelli (1846) was the first to propose that new cells are formed by the division of pre-existing cells.
Rudolf virchow (1859) proposed “omnis cellula e cellula” and “cell lineage theory”.
A cell divides when it has grown to a certain maximum size which disturb the karyoplasmic index (KI)/Nucleoplasmic ratio (NP)/Kernplasm connection.
Two processes take place during cell reproduction.
Cell growth: (Period of synthesis and duplication of various components of cell).
Cell division: (Mature cell divides into two cells).
Cell cycle: Howard and Pelc (1953) first time described it. The sequence of events which occur during cell growth and cell division are collectively called cell cycle. Cell cycle completes in two steps:
Interphase
M-phase/Dividing phase
