History of the Cell

The historical word cell of the cell was created by British Robert Hook (1635-1703) under the microscope. The word cell comes from a Latin cellar. Microscopy creates new possibilities in research biology, which allows scientists to study new perspectives in cell biology. Galileo is considered an invention of a microscope. The two major pioneers used in the microscope were Robert Hook and Antony von Liwen Hook.

In this month's article Paul Nurse outlines somatic development of cellular theory, one of the most important theories of biological history. This suggests that all forms of life are composed of cells. In the process, he lists the wonderful molecular complexity and processes discovered while himself and others are studying cell life. In particular, nurses focus on the mechanism and control of cell regeneration that ultimately promotes growth, development and evolution.

Sir Paul Nurse: Cellular thinking, cytology is that all lives are composed of cells. In other words, a cell is a basic unit of life, a structural life unit. Second, cells are the simplest unit of life. In other words, it is the simplest entity that shows us the characteristics and phenomena related to our life. Cell theory - This is essential for understanding biology, as cells form the basis of all life. There are unicellular organisms such as yeast and other bacteria. Cell division, division of cells from 1 to 4 forms the basis for the growth and development of all organisms. If it comes to problems like cancer, of course, it is essential for illness. You can understand its importance ... this is a picture of the early mammalian embryo - the small black spots there all represent one cell. By emphasizing that each one of us consists of billions of cells, we can easily see the fetus.

Cell division is the process by which parent cells divide into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. In eukaryotes there are two different types of cell divisions: nutrient division where each daughter cell is genetically identical to the parent cell (mitosis) and the number of chromosomes in daughter cells is reduced by half Germ cell division. Gametes (meiosis). Meiosis produces four haploid daughter cells by performing one DNA replication followed by two divisions. The homologous chromosome is separated in the first part and the sister chromatid is separated in the second part. Both cell division cycles are used for sexual reproduction at certain stages of their life cycle. Both are thought to exist at the common ancestor of the last eukaryote
