Cytoplasm – a mandatory part of the cells attached between the plasma membrane and the nucleus, divided into hyaloplasm (the main substance of the cytoplasm), organelles (the permanent component of the cytoplasm) and inclusion (the time components of the cytoplasm).
The chemical composition of the cytoplasm: the base is water (60-90% of the total mass of the cytoplasm), various organic and inorganic compounds. The cytoplasm is alkaline. A characteristic feature of the cytoplasm of eukaryotic cells is a constant movement (cycloids). It is found primarily on the movement of organelles cells, such as chloroplasts. If the motion stops the cytoplasm, the cell dies, because only by being in constant motion, it can perform all the functions – cytoplasm function.
Hyaloplasm (cytosol) is a colorless, slimy, thick and transparent colloidal solution. It is in this flow all the metabolic processes; it provides a link for the nucleus and all organelles. Depending on the predominance of hyaloplasm liquid part, or large molecules they distinguish two forms of hyaloplasm: sol – a more liquid and gel hyaloplasm – thicker hyaloplasm. Between them is possible inter transitions: gel turns into a sol and vice versa.
the union of all components of the cell into a single system
environment for the passage of many biochemical and physiological processes
environment for the existence and functioning of organelles.
Cell walls restrict eukaryotic cells. In each cell membrane can provide at least two layers. The inner layer is adjacent to the cytoplasm and presented to the plasma membrane (synonyms – plasma membrane, the cell membrane, cytoplasmic membrane), on which is formed by the outer layer. In animal cells it is thin and is called the glycocalyx (formed glycoproteins, glycolipids, lipoproteins) in the plant cell – a thick, called the cell wall (forming cellulose).
Structure of membranes
All biological membranes have a common structural characteristics and properties. Currently, generally accepted liquid-mosaic model of the membrane. The basis of the membrane lipid bilayer is formed mainly phospholipids. Phospholipids – triglycerides, in which one fatty acid residue is substituted for the remainder of phosphoric acid portion of the molecule, which is the residue of phosphoric acid, called the hydrophilic head regions, which are the remains of fatty acids – hydrophobic tails. In the membrane phospholipids are located in a very orderly: the hydrophobic tails of the molecules facing each other, and the hydrophilic heads – out to the water.
Here I am going to discuss about cytoplasm function. We all know that the body of a living creature consists of numerous and countless cells. The cell is the basic building block of the body of an animal or a plant. Each of these cells carries out numerous functions which are essential to keep us alive. Each of these cells consists upon a number of cell components and cytoplasm is one of them.
Cytoplasm is one of the very important components of a cell but before getting into the issue of cytoplasm function, it is important to have a basic knowledge on cells. The structure of the cell is an important issue as it is a crucial factor for carrying out cell operations. Each off these cells is separated from each other through a membrane called cell membrane. Cells can be categorized into tow basic categories depending upon the presence of nucleus and some other organelles. These tow categories of cell are, eukaryotic and prokaryotic. Prokaryotic cells don’t have nucleus and they are usually present in plant body where as a eukaryotic cell contains nucleus along with other cell structure components and they are usually found in animal body.
Anyway, we have spoken a lot about cells and it is time to enter into the issue of the cytoplasm. Cytoplasm is present in between the nucleus and the cell membrane, that is, it fills the gap between the cell membrane and nucleus. The liquid substance of the cytoplasm is called cytosol and another component is termed as hyaloplasm. The 80% off component of cytosol is water. The next paragraph describes the roll of cytoplasm behind cell activities.
However the structure of plant cells and that of animal cells are quite different but the role of cytoplasm is same in both cases. The main function of cytoplasm is to provide security to internal layer. The fluid acts as a shock absorber for the internal layers of the cell. The next high priority role of cytoplasm is, it preserves essential chemical substances which may be required by our body in future and acts as a medium for various essential metabolic reactions. It also allows anaerobic glycolisys and protine synthesis for our body. Cytosol helps to dissolves essential enzyme which are required to decompose various compound element into simple elements and to elevate the metabolism process. It also provides a means for exchange of various chemical substances and other essential materials in between cells which are required to keep all cells working properly.
