NEET BIOLOGY UNIT 17 CELL CYCLE AND CELL DIVISION INTRODUCTION W.Flemming at first studied mitotic division in Salamander. Strasburger discovered meiosis and gave name prophase, metaphase, anaphase, telophase. Meiosis name was given by Farmer and Moore. It is important for development, regeneration and reproduction. Hormone cytokinin increases rate of cell division. TYPES OF DIVISION AMITOSIS MITOSIS MEIOSIS AMITOSIS (No Spindle, No Chromosome) It is the simplest mode of cell division at first described by REMAK (1841). This type of division starts with elongation of nucleus. Nucleur division is followed by the division of cytoplasm its results in formation of two daughter cells. Nucleus becomes dumbbell shaped, and get divided into two daughter nucleus. In this division, no spindle formation and no distinct chromosome formation occurs. Nuclear evelope remains intact. The daughter cells are approximately the two equal halves of a parental cell. e....
