Animal Cell Model | The body unit or cell

---

Animal Cell Model Just as a house is built gradually by arranging one brick on top of another, it contains more and more objects, so the body of a human body or any living animal or plant is made with a single unit or cell forming another living body. Anybody, from animals to humans, is made up of living cells. Again, there are animals whose bodies are made up of just one cell. The smallest animals in the world are amoebae and monocytes. Their bodies are made up of just one cell. Again, the bodies of better animals are made up of many cells. Some cells are made up of a single banana or tissue. The human body is made up of so many issues.

 

Animal Cell Model Here a monocyte is depicted in an amoeba and a human body cell 

The body of monocyte is made up of a single cell, just as a human body is made up of many cells.

According to Robert Hooke, the unit of structure and function of living organisms is the cell that is capable of performing these functions on its own. The outer wall of the plant body is dead, the inner protoplasm is alive. It is called cell wall but the cell membrane outside the body of animals is made up of living matter. The substances that enter or exit the cell such as proteins, fats, carbohydrates, etc. But they are lifeless.

Often the cell membrane does not completely enclose the cell, but partially encloses it, and the protoplasm of the adjacent cell is attached to its protoplasm – as in the liver, in the pulse. When an external particle enters the cell through the middle of the membrane, there is a small hole and the particle falls into it. Then it deepens and surrounds the particle. Eventually, it enters the body. The things that the body needs in the cell can enter – what is not needed cannot enter.

The phagocytic nature of the cell is very similar to that of the amber diet. In the plant world, the vacuoles between cells are large but in the cells of animals, they are small. Moreover, plant cells contain plastids that animals never have.

Which is contained in a cell

1. The cell wall or cell membrane surrounds a cell. Through this point, the necessary objects can enter and exit. But not all objects.
2. Inside the cell there is a protoplasm which is another name for the cytoplasm. It is a complex substance.
3. The nucleus-The nucleus is often referred to as the “control center” of the cell because it contains the genetic material, DNA, which carries the instructions for the cell’s activities. It’s surrounded by a double membrane called the nuclear envelope, which has pores to allow the passage of molecules like RNA and proteins. Inside the nucleus, you’ll find the nucleolus, where ribosomal RNA (rRNA) is synthesized, and chromatin, which consists of DNA and associated proteins. During cell division, the nucleus undergoes a series of complex processes to ensure the accurate segregation of chromosomes into daughter cells.
4. Mitochondria – These are tiny long substances that help the cell to nourish and breathe.
5. Golgi Bodies – These are located near the nucleus and help in the secretion of cells.
6. Centrosome– It is formed by thickening a small part of the cytoplasm. It is close to the nucleus and helps in reproduction.
7. Lysosomes– These are full of fluid or help in the digestion of tiny particles in the cell. Protoplasm is a living substance. Protoplasm is made up of various elements like carbon, hydrogen, nitrogen, oxygen, sulfur, phosphorus, calcium, sodium, potassium, etc. But if those substances are thrown in the laboratory side by side, it does not yield living cells. So living cells are an absolutely wonderful object. Humans have not been able to create a living cell in a laboratory despite many attempts. However, efforts are underway. Science is moving forward. I don’t know what the future holds.

Nucleus

The heart of a cell is its nucleus. Its upper covering is the nuclear membrane. It contains liquids or nuclear sap and many fine thread-like substances called chromosomes. Numerous chromosomes combine to form a chromatin network.

Now the number of these chromosomes is different for each organism due to the difference in nature. The nature of their character and structure all depends on the number and nature of the chromosomes in this nucleus. The main substance of this chromosome is called ‘Dean’. This dean is the substance that is the main source of all the action of chromosomes. Its chemical name is Deoxy Ribose Nuclei Acid or Dean for short.

Depending on the number of these chromosomes, there may be cross-breeding of one plant or animal with another. Suppose an animal has only 25 chromosomes in its cell nucleus. Each cell in the body of a particular animal will have the same number of chromosomes. In reproduction, a male gamete and a female gamete combine to form a zygote. There are 26 male chromosomes in 25 female chromosomes.

So in the body of an animal that has 25 chromosomes in the nucleus, their thick female nucleus will match the zygote. But if the nucleus of an animal cell has 25 chromosomes and another animal has 26,27, or 23,24 chromosomes, then their mating creates a zygote. As a result, the mule is associated with the father and mother. This is because their male and female animals have an equal number of chromosomes in their body nuclei. But donkeys having sex with a dog will not have any offspring because the number of chromosomes in the nucleus of their cell is not equal so that is the case.

If cross-breeding of gorillas with humans is possible, it could lead to the creation of new creatures. This is because the number of chromosomes in the nucleus of their body cells is equal. Lions and tigers were cross-bidded at the zoo in Kolkata. But cross-bidding of donkeys, horses, elephants, goats, etc., or tigers with humans, will not be possible to produce a child.

Similarly, in the plant world, the nucleus of every plant cell contains a certain number of chromosomes. Therefore, as a result of pollination, the female flowers of a particular tree are pollinated and the fruits are formed only when the male flowers are pollinated. When the pollen of another flower comes, there is no fruit. So papaya, mango, blackberry, jackfruit each fruit is formed according to the specific character. So a huge focal point of the biosphere is the number and character of the chromosomes in their nucleus.

The main reason that the character of the parents is transmitted to the child is the chromosome and the dean. The nucleus of a human cell contains 46 chromosomes.

Different substances in the cell

Chemically analyzing all the substances in a single cell or cell, the object that is found is-

1. Proteins are complex substances whose structure is complex and which cannot be made in the laboratory, despite much research.
2. Fatty substances.
3. Carbohydrates.
4. Various national salts. The main ones are phosphate and chloride of sodium, potassium, and calcium.
5. Water.

Structure and function of different tissues

Many cells are joined together to form a tissue. There are different types of tissues in the human body. Cell structures vary according to the difference in tissue structure. The cells are of different shapes, depending on the variety of tissues.

Various body fluids

Cells need water and soluble substances to maintain their health. The fluid that enters and exits the cell is called body fluid. There are some fluids in the cell – there are some outside the cell. Due to the movement of these fluids in the body, the excretory substances are excreted from the body through sweat, urine, etc. Again new fluids are supplied to the body for work through drinking water. As a result, the body’s water balance is in the right way.

Excess fluid from the body can lead to death. Death is due to the lack of liquid plasma in the blood of the body. For this, a mixture of water and salt is then injected intravenously at a percentage equal to the body’s plasma salt. It is called saline injection.

Clinical Note– Saline is usually given in two ways. That is the open process and closed process. Normal saline is formed by dissolving as much salt in the body’s plasma as salt. He is heated to the equivalent of body heat. Then it is given intravenously.

If the vein is found to be clear, the needle is inserted between the two walls of the vein to hold it in place, and saline is slowly absorbed into the bloodstream. If the vein is not clearly visible, then the skin on the side of the vein should be cut parallel to the vein and left on the side. As a result, veins can be seen. Then saline is given in it by inserting a needle. Call it an open process. The saline vessel is high with a narrow tube and a needle at its tip. Care should be taken so that air does not enter it.

Different body fluids

Now we are talking about different body fluids. These fluids are-

1. Intracellular Fluids

It is the fluid between different cells. This fluid is 50 percent of the total body weight. Fluids are predominant in each of the many tumor cells throughout the body.

2. Extracellular or Interstitial Fluid

These are the extracellular fluid. The small gap between different cells is called intracellular space. This is where the fluid lies. These fluids make up 30 percent of the body’s total fluid. Because of these shots, the fluid in the cell is exchanged. As a result, nutrients, food, salt, oxygen, etc. are supplied to different cells.

3. Blood Plasma

Blood is made up mainly of plasma or fluid and particles and the amount of plasma in the human body is 5% of the total body weight (about 3 liters) and the total amount of blood in the human body is 5-6 liters. This plasma does the work of transporting the body. The exchange of blood plasma with interstitial fluid does not take place directly. Plasma has high blood pressure or hydrostatic pressure! So this exchange is done by osmotic process or Fluid Exchange. Plasma does not contain interstitial fluid.

Tissue fluid exchange

Plasma fluid has a higher pressure or mechanical hydrostatic pressure which is much higher than interstitial fluid. So the fluid tries to get out of the capillaries. Plasma contains protein but does not contain interstitial fluid. So plasma proteins give an osmotic pressure that causes fluid to enter the capillaries. Mechanical and hydrostatic pressure at the end of the arteries of the capillaries exceeds the osmotic pressure so that fluid enters the tissues in the pressure balance. Again the hydrostatic pressure at the Venus end is low. As a result, less fluid enters the capillaries than the osmotic pressure passes through them. This excess fluid flows through the middle of the lymph.

The exchange of fluids between the inside and outside of the cell depends on the osmotic pressure. But the membrane outside the cell has a capacity to absorb and store certain substances. He is called Selective Pamiability. For him, substances like carbon dioxide, oxygen, urea, etc. travel through him and other substances cannot do that. Sometimes one substance can only come out and the other can only enter. For example, the intracellular fluid contains potassium but sodium is discarded.

Clinical Note– There are more or fewer fluids in the patient’s blood in two different ways. These are 1. Lack of liquid water in the blood leads to thirst, mental distress, and fever. 2. Liquid water in the blood is fine but salt is reduced! Usually sodium salt is less. Both of these are then supplied with water and salt mixed with saline. Excessive sweating depletes the body of salt, which cannot be replenished by water alone but requires salt and water.

When the capacity of the kidneys decreases, sodium is increased. On the other hand, if only glucose is injected in large quantities without sodium, then there may be various difficulties in the case of fluid depletion. The best remedy for dehydration is normal saline mixed with water and salt.

Edema is the result of excess water accumulating in the swollen tissue. There are usually four reasons for this Oedema. That is-

1. Excessive mechanical and hydrostatic pressure is on the capillaries. This can happen even if the flow in the vein is blocked.
2. Osmotic pressure is very low due to low plasma protein.
3. 3. Lymphatic ducts become blocked and lymph flow stops – as in filariasis.
4. 4. The walls of the capillaries are damaged. This causes the plasma protein to leak into the tissue.
5. 5. Congestive heart failure causes cardiac edema. If the kidneys cannot get rid of sodium, Oedema occurs in various parts of the body – such as nephritis.
