14 components of the animal cell structure

Animal cell

Identification of the structure of living cells is one of the most important data that we have to deal with. Animal cells are the main components of the body of organisms, including humans and animals, and the most important property of animal cells is that they are mononuclear cells, that is, they contain one nucleus. However, the nucleus is surrounded by a membrane called the nuclear membrane, which is different from prokaryotic cells. Prokaryotic cells are cells that do not surround the nucleus that contains the nuclear membrane, for example, the cells that make up the bacterium.
But how many cells are there in the human body? This is one of the most important problems, because the number of living cells in the body is unexpectedly very large and reaches about 100 trillion cells. Each cell in the cells of the body is divided into different types, such as differences in shape and size, and the functions that it performs. In addition to his life.
Cells that have the same shape and the same function together form a tissue called tissue. Animal cells are the main function of cells, because cells with different functions, forms and morphology are connected to each other, forming an organ.

What is the composition of animal cells?

Living cells are made up of very important groups of parts, each of which performs a specific and precise function. Next, you will learn about the components of animal cells.

Plasma membrane

The plasma membrane, which is an important and main component of the formation of living cells, consists of a very thin membrane and surrounds the cytoplasm of the cell. It also has many features that distinguish it, such as penetration, and it also differs in options.


The cytoplasm is also part of an important part of cell formation, which consists of a substance with a gel-like texture, and the cytoplasm is surrounded by a very important part of the cell, the cell membrane, the cell.


As for the nucleus, this is an important part, but rather the most important part in the cells of the body, which contains all the genetic information about the cell. It acts to regulate the process of conversion of proteins into it, and most importantly, to distinguish the nucleus, it contains the genetic material of the cell, and the nucleus also contains the so-called nucleus (nucleus). And the core is part of an important part within the core. The nucleus is surrounded by a shell called a nuclear shell, which contains a very precise hole, called a nuclear pore. The main role of this hole is to function to pass both amino acids in addition to protein.


Concentrated liquid is a group of cylindrical structures that are bundles of nine thin tubes, the main task of which is the organization of cell division.

cilia and flagella

Cilia and flagella are a group of specialized and thin tubes that support the migration of animal cells. It is also very useful for transporting liquids, in addition to other groups of substances around resting cells in multicellular organisms.


The cell structure consists of a set of fibers distributed in the cytoplasm of the cell, in the form of a network, the main function of which is to support the cell while maintaining its shape.


The endoplasmic reticulum consists of groups of tubes connected to the nuclear membrane of cells. Its main task is to transfer substances between the nucleus and the cytoplasm. It makes a significant contribution to the development of compounds and functions for processing and moving them in and out of animal cells, so the endoplasmic reticulum consists of two types. They are:
A rough endoplasmic reticulum containing the so-called ribosomes.
• Smooth endoplasmic reticulum does not contain ribosomes.

Golgi device

The Golgi apparatus is an important component of cells and performs the functions of producing, storing and exporting a group of molecules produced by cells, such as proteins and fats.


The current body is a group of organelles that act by digesting and destroying certain cellular molecules, and these molecules no longer need cells, so they can be reused as new building materials for cells. Works to break them into groups of smaller parts.


Microtubes consist of a group of hollow cylinders that are enclosed in the cytoplasm of eukaryotic cells and play a role in both transport and cell support.

Micro thread

A thin string is a strong structure in the form of a bacillus, which is an important component of the intracellular cell structure.


Mitochondria are a group of organelles present in all eukaryotic cells that generate energy inside the cells, and are also one of the parts where the so-called cellular respiration takes place.


This is a group of spherical particles surrounded by a single membrane A group of enzymes that help detox alcohol, they also work to break down fats in cells.


Ribosomes are a group of very small organelles in eukaryotic cells, whose main role is to create proteins that, in addition to proteins, consist of so-called ribose DNA.

What are the most important animal cell types?

As mentioned earlier, the body has a group of different types of cells, each of which has a different shape and size and, thus, performs a certain function. Below we list the most important types of cells in the body and the most important functions that they perform.

stem cells

We can say that stem cells belong to a non-specific type of cells, but at the same time they can transform into specialized organs and, therefore, transform into tissues. The most important property of stem cells is that they can multiply several times, which allows them to play a very important role in transplantation of various organs to restore damaged or damaged tissues and in many diseases. We will also go into specialized procedures.

bone cells

As for the cells that make up the bones of the body, they are composed of groups of bone tissue that work to form bone tissue, and the human body contains the following three types of bone cells.
Osteoclasts. A group of cells that destroy useless bones in the body and use them in new bone formation processes.
Osteoblasts, cells involved in the generation and construction of bone.
Bone cells are a group of adult bone cells that maintain calcium balance in bones.

blood cells

Blood cells are the main components of human blood and are divided into two types: red blood cells and white blood cells.
