Question

What is cell division? Write two types of cell division?

Answer 1

• The cell cycle is the series of events that take place in a cell leading to its division and duplication of its DNA to produce two daughter cells. In eukaryotes, the cell cycle is divided into three periods which are interphase, the mitotic phase, and cytokinesis.
• During interphase, the cell grows, accumulates nutrients needed for mitosis, preparing it for cell division and duplicating its DNA. During the mitotic phase, the chromosomes separate. During cytokinesis, the chromosomes and cytoplasm separate into two new daughter cells.
• Cell division is the process by which a parent cell divides into two or more daughter cells. The primary concern of cell division is the maintenance of the original cell's genome.
• Before division can occur, the genomic information that is stored in chromosomes must be replicated, and the duplicated genome must be separated cleanly between cells.
• In eukaryotes, there are two types of cell division. One is a vegetative division where two daughter cells are formed and each daughter cell is genetically identical to the parent cell. This type of division is called as mitosis.
• The other type of cell division is a reproductive cell division where four daughter cells are formed and the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes. This type of cell division is called as meiosis.
