Earth constitutes of countless number of living things and every organism is made up of cells. Every human body comprises of trillion of cells, the cells make you. They are of different shapes and sizes depending on their functions. The most common cells found in the human body are skin cells, nerve cells, brain cells, each cell perform thousands of different functions. They combine to form tissues, however they don’t live for ever. They reproduce, regrow and die
Cell Division – A small Overview
Cell is the basic building block of all living organisms in the environment. They usually reproduce by duplicating themselves diving into new cells called daughter cells. Mitosis undergo five stage process of cell division. During these stages the cell will undergo mitosis to form 2 nuclei. Single celled organism called as prokaryotes or bacteria doesn’t undergo all these complete stages and uses the binary fission method whereas multicellular organism like plants and animals or typically referred a eukaryotes has to under many rounds of mitosis through asexual mode for their growth and development. However sexually reproducing eukaryotes uses special form of division called meiosis.
How Cell Cycle Works
Most eukaryotic cells follows a process of growth and division, this is generally called as cell cycle. The cell cycle usually begins with the growth stage also referred as mitosis when the cytoplasm condenses and the stage is completed with cytokinesis where the division of cytoplasm takes place and the nuclear membrane is formed around each pair of chromosomes. During all the stages the cells undergo growth and metabolic activities.
To summarize the entire life cycle of cells, the cell is preparing to grow and divide during the initial phases of mitosis and the division of the cells gets completed in cytokinesis with cytoplasm divides into two daughter cells.
