A common and adaptable food in many homes is eggs. They provide vital proteins, vitamins, and minerals that are needed by growing children and families, making them a significant source of nutrition. Gaining knowledge about eggs outside of the kitchen will assist you in choosing better options for your family’s diet.
Despite the egg’s seemingly straightforward structure, each component serves a distinct purpose and adds to the food’s overall nutritional value. Every part of an egg, from the yolk to the shell, contributes to its health benefits.
It’s crucial to know how to assess both the quantity and quality of eggs. The safety and flavor of this well-liked food are affected by the freshness, quality, and storage methods of eggs. Making educated choices regarding the eggs you purchase and eat as a family can help lead a healthier lifestyle.

What is it?
A female body’s reproductive cell is called an egg. It is frequently referred to as an oocyte. With the possible exception of certain nerve and smooth muscle cells, it is regarded as one of the largest in the human body. A single living thing is an egg. This is a true work of art that nature produced to preserve humankind. It was previously thought that the development of the human embryo was exclusively the function of the male reproductive cell, or sperm. Since the egg plays a direct role in the development of the embryo, science and medicine have changed their perspectives on eggs.
Eggs are monogamous by nature. This means that its fusion is possible only with one of the millions of sperm that move along the female genital tract after ejaculation. Sometimes two or three sperm cells penetrate the egg cell at once, but such an embryo is doomed to die – its genetic makeup cannot be normal. The ovaries – the female sex glands – are responsible for the production of eggs. First, a large number of primary cells – oogonia – are formed in them. Then, significant changes appear in the structure of these precursors at the intracellular level. The third phase of development is the maturation of the egg cell. Only a mature egg cell can leave the follicle, this process is called ovulation.
Structure
The structure of the female egg cell is very complex. Everything in it is designed to provide the best environment for the development of new life. The size of a woman"s reproductive cell is 0.1-0.15 microns. A large round cell is immobile. It is this feature that makes the task easier for spermatozoa. If the egg moved, fertilization would be more difficult. In the structure of the cell, as can be seen in the structure of the structure, the cytoplasm, the core and the membrane are clearly defined. The outer membrane of the cell has a multi -layer structure. Each of the components performs its main functions. The shells are arranged so that after the penetration of one spermatozoa into the cage, they become completely impermeable for other male cells. At the same time, the shells have a sufficient margin of safety, so that when transporting the eggs along the phallopium pipe into the uterine cavity after fertilization, the crushing cage does not suffer and is able to safely complete its “journey” and implanted.
The nucleus of the egg contains enough proteins to support the division and growth of a new life. The chromosomal set X is also present in the core. A cage is deemed "defective" if the egg lacks a chromosome, rendering it unsuitable for fertilization. After fertilization, the cell’s protoplasm houses nutrients and RNA required for the next stage of division.
Eggs are an integral component of our diet, providing vital nutrients, distinct structural qualities, and important roles in both cooking and nourishment. Families can make more informed decisions when it comes to ensuring fresh ingredients, balancing nutritional needs, and promoting the healthy development of their children when they are aware of the quality, quantity, and significance of eggs.
How are they formed and developed?
When a mother carries a girl under her heart and does not yet suspect that her fetus is female, cells that are precursors of eggs are already developing in the baby"s ovaries. They are called first-order oocytes. A female fetus has tens of millions of them. But these cells are not strong and viable, and therefore the vast majority of them die. By the time a girl is born, about two million cells remain in her ovaries, and by puberty their number reaches only 400-500 cells. This amount is for life. This supply of oocytes is strictly defined, it cannot increase or decrease. Then the first-order cells develop in the follicles. The hormonal background, sensitivity to its changes allow the follicles to independently regulate these processes. During puberty, under the influence of female sex hormones, the follicles increase in size, some eggs mature, the development of others is artificially inhibited so that the supply does not quickly run out.
One egg grows in one follicle. In the first phase of the menstrual cycle, several follicles grow, but only one of them will become dominant. A mature sex cell, ready for fertilization, will “hatch” from it. The older a woman becomes, the fewer immature eggs she has. After 40 years, the supply is almost exhausted. Some of the oocytes mature and come out, while others have undergone degeneration, the precursors of the eggs have died. With the onset of puberty in a girl, the first-order oocytes turn into second-order oocytes, which have half the set of chromosomes. 23 pairs is the “contribution” that a woman makes at the moment of fertilization. Exactly the same number of pairs of chromosomes are “given” by the male sex cell. By the time of ovulation, the size of the egg reaches its maximum, the follicle ruptures and the egg enters the fallopian tube. There it can wait for the sperm for 1-2 days, after which, if fertilization does not occur, the cell dies, after two weeks the woman begins her period. The process is repeated in a new cycle.
| Aspect | Details |
| Structure | Eggs consist of the shell, egg white, and yolk, each serving a specific function. |
| Functions | Shell protects, egg white provides protein, yolk contains fats and vitamins. |
| Quality | Fresh eggs have firm whites and round yolks. Quality decreases with age. |
| Quantity | One egg contains about 6 grams of protein and 70 calories on average. |
Eggs are an essential food in many households because they are nutritious and versatile. Recognizing their many applications in baking and cooking requires an understanding of their structure, from the shell to the yolk.
When selecting eggs, quality and freshness matter because they have a direct bearing on taste and safety. Basic examinations, such as the float test and a look at the shell, can have a significant impact.
Egg recommendations can change depending on factors like age, diet, and medical requirements. They provide both adults and children with important nutrients and a valuable source of protein.
