Primary Cell and Secondary Cell

Let us know in brief about the primary cell and the secondary cell.

Primary cell culture can be defined as a type of cell culture that consists of cells that can be directly obtained from the host issue. We can find two types of primary cell cultures based on their cell growth. One is adherent culture and another one is suspension culture. Adherent cultures require a connection or attachment for growth while in the case of Suspension cultures cells grow in the medium. As a whole primary cell culture poses a very small amount of life span.

Secondary cell culture can be defined as a culture that has an unlimited lifespan. It is possible because of the mutations done by them. Secondary cell cultures can easily sustain for longer generations. They have more cells than primary cell cultures and have greater cell density (optimal). It canes more than Primary cell structures also due to its viral transformation. Thus we come to know about primary cells and secondary cells.

About a Few Important Parts of Cell

Before knowing about primary cells and secondary cells and primary cell and secondary cells examples we have to know about the parts of a cell and the differences of a few important of them.

The cell membrane is an important part of a cell it separates the contents of a cell from all its surroundings and it helps to maintain the shape of the cell whereas a cell wall is needed to give rigidity and shape in plant cells. Talking about cytoplasm has different organelles contained in it which perform define functions. All the metabolic activities of this cell occur in the cytoplasm. It is also the medium of respiration in the initial stages. It contains a mixture of water and soluble inorganic and organic compounds and various organelles.

Mitochondria is the powerhouse of cells and is used to produce the energy in a cell in the form of Taper if it is off very but is usually sausage-like. It has a double-walled inner wall thrown into folds. They have them and contain their ribosomes. You must be wondering what ribosome’s are: they are small granules either scattered in the cytoplasm or attached to the outside of the endoplasmic reticulum. All these can be found in the primary cell and secondary cell.

Detailed Explanation about Primary Cell and Secondary Cell

Primary cells Originate from tissues. They are directly taken from tissues and are not modified. They provide excellent systems for studying the biochemistry of cells and are effective in the studying of drugs and toxic compounds in the cell. 

The advantages of the primary cell are that it allows experiments on human tissues and the use of it provides better results than cell-lined cells. They are cost-effective and help in reducing the cost of animal models which are required for studies. The disadvantages add that they take more time to grow and have limited growth and the cost of isolation is often high.

Talking about the secondary cells they are homogeneous and can adapt to any conditions and have altered genetic metal and can bypass aging and are easy to maintain. The advantage of it is that it can last for more generations and one of the disadvantages is that it serves in vitro models which are very costly.

Both types of cells have similarities in some kinds and different others. The similarities are that they allow growth of sales and maintenance of cell functions regularly to a great extent and there are dissimilarities R their homogeneity their origin of cells their genetic makeup their optimal sentence and their life span. Thus we come to know in detail about primary cells and secondary cells.

Some primary cell and secondary cell examples are –

Primary-muscle cells, epithelial and endothelial cells.

Secondary cells-Wood cells

What is the Primary and Secondary Cell Wall?

The primary wall of a cell is the layer that contains cellulose and is laid down by cells that are dividing and growing cells. This secondary wall can be found in some plant cells which are located between the plasma membrane and primary cell wall. Secondary cell walls are responsible for providing additional or extra protection to the cells and adding to the strength of the larger plant. The secondary cell wall consists of Cellulose and other substances such as lignin and glycoprotein. One fine example of the secondary cell is wood, some cell walls also store nutrients that could be used by the plant later. By now we have understood what is primary and secondary cell wall.

Conclusion

By now we have come to the end and have understood about the primary cells, the secondary cells and their examples of what primary cell walls and the secondary cell wall is. We have also studied in detail. We also know the advantages and the disadvantages of both types of cells. Humans have evolved from cells from tiny microorganisms to present-day humans. We have come a long way and have emerged into being one of the most intelligent and advanced races on the planet. It is because of the evolution of the cells that we are here today. Evolution is a part of human history and it is the evolution that has made millions of things possible on earth and cells are responsible for all the above.
