Web1. Cell division is a pre-requisite for the continuity of life and forms the basis of evolution to various life forms. 2. In unicellular organisms, cell division is the means of asexual reproduction, which produces two or more new individuals from the mother cell. The group of such identical individuals is known as clone. Web7. If the organisation of a cell is destroyed due to some physical or chemical influence, what will happen? Solution: In the event of any damage to cells and when the revival of cells is not possible, Lysosomes burst, and enzymes digest such cells. This is why lysosomes are often referred to as ‘suicide bags’. 8.
WebM Phase (Mitosis phase): This is where the actual cell division occurs. There are two key steps in this phase, namely cytokinesis and karyokinesis. G0 Phase (Resting Phase): The cell neither divides nor prepares itself for the division. G1 Phase (Gap 1): The cell is … In each cycle of cell division, two daughter cells are formed from the parent cell. … WebApr 6, 2024 · Mitosis is the process of cell division. It is a stage of the cell cycle in which newly formed DNA is separated and two new cells with the same number and type of chromosomes as the parent nucleus are formed. Except for germ cells, most eukaryotic cells divide in such a way that the ploidy or number of chromosomes remains constant.
WebMitosis. The process of division of parent cell into two new identical cells is known as mitosis. In both the new cells, the number of chromosomes remain same. Mitosis (cell division) occurs only in eukaryotic cells. In … WebThe division of the cell is initiated by division of the nucleus i.e. Karyokinesis followed by division of cytoplasm i.e. Cytokinesis. The stages of karyokinesis are – prophase, metaphase, anaphase and telophase (Fig. 2.4). Prophase: In the resting nucleus the chromatin is spread out as a network.
