The last stage of — maturity and aging. At this stage, the body reaches full maturity and begins to age. Individual cells begin to die, which leads to a decrease in the functionality of organs and systems of the body.
organism goes through a sequence of stages, each of which plays an important role in the formation and functioning of the body.
At the first stage, the zygota is divided, as a result of which the — morule is formed, a spherical structure consisting of a small number of cells. Further, the morule proliferates and forms a blastula consisting of blastomers — small, tightly packaged cells.
In the process of further development, the blastula undergoes emdr therapy gastrubation, as a result of which the gastrula is formed. Gastrula consists of three germ cell layers — external epidermis (ectoderma), internal entoderma and mesoderma, ensuring the development of different organs and tissues.
These germ cell layers will differentiate and specialize in specific cells and tissues, forming the heart, nervous system, muscles, skin and other organs.
Thus, primary cell formation is a fundamental stage in the development of multicellular organisms, during which the zygote turns into a complex structure consisting of various types of cells and tissues.
Cell reproduction occurs through division, which can be of two types: mitosis and meiosis. In mitosis, the cell is divided into two new cells having identical genetic material. In mitosis, processes occur, such as DNA replication, chromosome condensation, and chromatide segregation into new nuclei. Meyoz, on the other hand, is a form of cell division that occurs during the formation of — sperm and eggs. As a result of meiosis, four cells with a puberty of chromosomes are formed.
