Cell
cell English: (Cell)
is structural and functional unit in living organisms, all living organisms are composed of one or more cells, producing cells of cell division after the growth process. Usually divided cells to plant cells and animal cells, and there are other divisions; and called a similar group of cells in the installation, which leads together a specific function in the neighborhood many cell tissue object. Cell and contain smaller objects called organelles, such as Golgi, and there is also a nucleus that carries within it the genetic code DNA er (Riboza DNA undiminished oxygen). Also surrounds the cell membrane called the cell membrane, and the plant cells, a wall of cellulose , called the plasma membrane, which is a flexible cellular Kalgsha.
Installed
eukaryotic cells comprise the nucleus of four main parts: the
cell membrane.
Nucleus.
Cytoplasm.
Cytoskeleton.
In other parts of the inside the cell, which usually hangs in the protoplasm include: the
lattice plasma.
Golgi.
lysosomes
mitochondria

microscopic view of a cell with a real nucleus Alprameseyoum
all cells that possess a real nucleus of nuclear cover a wall multiplier called real the nucleus.
prokaryotic
this division germs (bacteria) and blue - green algae. divided non - real cell nucleus into two parts cytoplasm ( the cytoplasm) and is similar to the nucleus called the nucleolus sometimes region, surrounded these two parts Alalgsha cell phone . This membrane is sometimes surrounded (as in some bacteria, and algae) cell wall solid or semi - solid maintains the cell and believes in her support. It is a real size of the cell nucleus rate ranges between 1-10 micrometers. and the cell can not continue living if its membrane was damaged. This involves the plasma membrane in some non - eukaryotic component folds and folds, but these are not separate from the plasma membrane, so it does not consider internal structures of some of these folds medium particles and be a container on the core enzymes necessary for the process of aerobic respiration, which occur in the mitochondrial (mitochondria) affiliated real cells kernel, but the lack of a permanent internal membranes means no local concentration of events and activities specific membrane and this is the main difference between the two types. Ribact also vary (Alrebozumat) in non - eukaryotic where the smaller diameter ranges between 150-200 angstrom and be free in the cytoplasm. There is in eukaryotic, in addition to the cytoplasm, with irregular shaped dense regions, namely the nuclear areas. The loss of membrane separator between the genetic material and the cytoplasm a fundamental difference between the two types of cells (non - eukaryotic and eukaryotic (. The
basic types of cell
are all cells are the basic units for living creatures. There are different shapes and sizes. Also vary depending on the function performed by the living creatures. common to all cells in the recipe formality is the cell membrane , as in the following manner: the
primitive cell nucleus from the left smaller and less complex than the real cell nucleus for the right size. is maximized primitive cell nucleus for the purpose of comparison.
cellular membrane, is a special barrier helps to control what goes into cell and what comes out of them. for the cells are usually a number of common functions. for example , contains all the cells and genetic material gives information and instructions for the cell to produce the materials you need. as the decomposition of molecules cells to produce necessary for the metabolism of energy. The Department scientists cells into two groups, namely: the primitive cell nucleus, as it can be seen from the above chart that the real nucleus of cells larger than the primitive cell nucleus, but may increase the size of it a hundred times. the scientists put the cells into two groups; based on internal Trakiphma. Both are contained cellular membrane, but the one containing distinct internal structures called organelles , a private structures are specific functions.
Peristaltic true cell nucleus nucleus and other organelles surrounded by membranes; the nucleus are privileged central organelle containing the genetic material RNA undiminished form of oxygen. Organelles allows the cell to carry out its functions in different parts of the cell at the same time. Most living creatures from the real cell composed the nucleus. Also, some of the only living creatures cell - including some algae and yeast - of real creatures nucleus. The primitive cells are the nucleus cells have no nucleus or organelles surrounded by a membrane. Most of the cell only living creatures - including bacteria - primitive cells nucleus; so called primitive cell nucleus.
The function of the cell membrane
that maintain the balance of the internal environment for living creatures called internal equilibrium process, which is necessary for the survival of the cell. The plasma membrane is one of the compositions mainly responsible for the internal equilibrium; it is a thin flexible barrier interval between the cell and its environment allows the passage of nutrients into the cell and exit of waste and other materials. Each primitive and real cell nucleus cellular membrane is separated from the liquid environment in which they exist. The permeability optional feature one of the important characteristics of the cell membrane; the cell membrane allows the passage of some materials to the cell and prevents other traffic.
