These are the 8 curious functions of the cells of your body that you did not know

Cells are of great importance for life, and they must fulfill certain functions for organisms to exist. Because of this, today we bring everything related to the question of what are 8 o’clock cell functions and its types.

What is a cell?

Before understanding everything about cell functions, it is necessary to start by knowing what is a cell.

The first and main thing to know is that it is the most basic unit that makes up all living beings. Something like this means that there is no living organism that is not made up of at least one cell. Such is the case of bacteria and in a certain respect viruses, although for the latter there is much discrepancy.

Speaking in detail about the cell functions, it is necessary to understand what the cell theory is. It was proposed by scientists in what were the years between the seventeenth and twentieth centuries, although it was really accepted since 1838. It proposes that all living beings in the world are made up of cells, which are organized in various levels of functional complexity and structural.

Everything that was the discovery of the cell has been considered the first step in regards to the modern study of life or modern biology. Since it allowed to understand in depth how complex living beings are. Laying the foundations of many of the later sciences.

With respect to what is a cell, It is good to know that the size that these have is quite varied. This will depend on the functions it performs and the degree of complexity that it possesses. Some are invisible to the eye, but others are not. The estimated size of a cell is approximately 10 microns.

What are the functions of the cell?

There are three main cell functions that are fundamental to life.

Relationship: They relate living beings to the environment and at the same time respond to the environment.

Reproduction: It is the procedure in which new cells are formed, starting from a stem cell. All through cell division that can be meiosis or mitosis. This will depend on the class of cell whatever it is and the stage of the cycle in which it is.

Nutrition: This is where the assimilation, incorporation and transformation of food takes place. So the cell you have the ability to create your own stuff.

Now, in reference to the cell functions and especially nutrition, you have to know that there are two types. In the first place we have autotrophic nutrition, which is where the matter that is inorganic is incorporated. And secondly we have heterotrophic nutrition, where all the matter that is organic is captured.

Besides this, there are other cell functions that are of great importance and those are the following:

Structural: As in the case of bones, fat and muscles, cells make up tissues that support organs and the body in general.

Metabolic: In this case, they are in charge of energy management. Decomposing the nutrients or in their difference transporting them through the body. As with digestive cells or red blood cells, which are responsible for transporting oxygen in the blood,

Secretaries: It means that they are responsible for the production of substances that are essential for life and also for its self-regulation. Examples of this are the cells that make up the glands or those of the mucosa.

Defensive: They help to keep the body clean and defend it from foreign agents as well as diseases.

Control: Another of the cell functions is control and an example of this is neurons. Allowing body coordination to occur and articulating all parts in an orderly way. Transporting the information and at the same time generating specific reactions.

What parts do cells have?

When talking about what is a cell, you should also know a little about its parts. Depending on what kind of cell that is, the parts may be different. In the simplest expression, the component parts are generally 3.

Cell nucleus: This is a part that only eukaryotic cells have and is surrounded by another part called the cytoplasm.

Cytoplasm: It is a liquid found in the cytosol. This being the place where all the elements that are particular to each cell float. As with ribosomes, DNA, mitochondria, among others.

Plasma membrane: All cells have a membrane that serves to delimit them, differentiating them from the outside. You have the ability to allow substances to enter and exit at your convenience. In this way, the cell is able to let in various nutrients and excrete all waste or waste.

What are the cell types?

In addition to knowing about the cell functionsIt is also important to know about cell types. They are classified into various types depending on the context in which they are mentioned.

According to your cell nucleus

Depending on whether the cells have a nucleus or not, they can be classified into two huge groups:

Eukaryotic cells

Eukaryotic cells are all those that have a defined cell nucleus. Said cell nucleus is found inside a nuclear envelope where its function is to maintain the integrity of the genetic material.

The process of cell division in all cells that are eukaryotic occurs through what is known as mitosis and DNA is much more complicated. In the case of this type of cell, its plasma membrane has carbohydrates, sterols and its ribosomes are much larger. When organisms are made up of these cells they are called eukaryotes.

Prokaryotic cells

They are all those that do not have a defined nucleus, therefore, their genetic material is dispersed in the cytoplasm. For this case, organisms that have prokaryotic cells originate through binary division. It means then that their DNA is not as complicated as in the case of eukaryotic cells.

Unlike the previous case, prokaryotic cells do not have sterols or carbohydrates in their plasma membrane, and their ribosomes are much smaller. If organisms are made up of prokaryotic cells, they are called prokaryotes.

According to its function

Taking into account the functions that cells must perform, they can be classified by receiving the name of the part to which they belong within the body.

A fairly simple example is somatic cells that come from stem cells that originate in embryonic development. They suffer from a process of apoptosis and cell proliferation. What is opposed or the opposite of these cells are the so-called germ cells and from which the gametes are formed.

Mother cells: They are located in all organisms that are multicellular and have the ability to divide through the process of mitosis. Thus generating two cells that are identical and have specialized cell lines.

Somatic cells: They receive this name because they are responsible for caring for the growth of all tissues and organs. As for example in the case of bones, skin, among others. When somatic cells mutate, they could be the main cause of cancers, especially colon cancer.

According to the kingdom of nature

Depending on the type of organism to which the cells belong, it can generally be divided into two groups:


Animal cells are a class of eukaryotic cells, which are responsible for forming the various tissues that animals have. Following this, these cells have a cell envelope that is made up of a cell membrane. As well as by the cytoplasm, in which all the organelles and the cell nucleus of the same are found.


They are also a type of eukaryotic cells, where their nucleus is delimited by a plasma membrane. All plant cells contain a vacuole that is responsible for storing and transporting water, waste and nutrients. It also has parts called plastids where its function is to synthesize food. And the chloroplasts where the process that all plants carry out called photosynthesis occurs.
