Cell components.. Cell membrane. Cytoplasm. Cell nucleus. Mitochondria



The different cells have a similar basic structure, some of which are:
1 - Each cell surrounded by the cell membrane: a thin envelope of fatty molecules interspersed with sperm molecules.
The cell membrane surrounds the cell and is separated between the cell and its environment.
Cytoplasm: A water solution that fills the cell cavity and swims all the organs. The cell gives the wet environment.
3. Cell nuclei: present in most cells, the most prominent and largest in the cell.
The nucleus of the cell contains the genetic material called DNA, which is transmitted by heredity from parents to offspring and contains information for the production of various proteins.
These proteins build cells and determine their shape.
In addition, there are macrophages that affect or stimulate vital processes in the cell.
In the absence of genetic material, the cell can not live for a long time and can not reproduce.
4- Mitochondria are: organelles in which cellular respiration occurs. In these organisms, cell-usable energy is produced in plant cells and animal cells, often by analyzing sugars by exploiting oxygen and releasing carbon dioxide (cellular respiration).
