Concept in Definition ABC

The concept of embryo can be used in our language to refer to various issues, although its most widespread use is the one that we will address first and that belongs to the area of biology.

Biology: an organism in full development

At the request of the biology, an embryo is that organism in full development, which It goes from its beginning in the egg, or failing that in the maternal uterus, and until all its organs are well differentiated, that is, it is the initial stage of the development of an animal or a human being.

Human embryo: process that extends from zygote to the seventh week of gestation and which differentiates its organs

In the case of human beings, we speak of an embryo until the end of the seventh week of gestation since fertilization occurred, after the seventh week it is spoken in terms of fetus.

Within biology, there is a branch called as embryology which is the one that exclusively deals with the study of embryos, a study that begins after the fertilization of the ovum, development, and continues until around the eighth week of gestation when the embryo.

In those organisms that reproduce sexually, the fusion of an egg with a sperm will lead to the formation of a zygote that will contain a combination of the DNA of both parents, mother and father.

After fertilization, the zygote will undergo a division process mobile that the number of them will increase, later, the famous cellular differentiation will take place that will promote the conformation of the various organs and tissues to give rise to the final organism.

Pregnancy, characteristics and symptoms

We call pregnancy the state of pregnancy that a woman will present and that indicates that the fertilization of one of the ovules by a sperm has occurred in her uterus. This situation occurs when the woman is in the so-called fertile days, that is, when her ovum is in an optimal situation to receive the gamete male and fertilization is generated that will give way to human pregnancy.

Pregnancy lasts an average of 38 to 40 weeks after the last female period.

Fertilization will take place in the fallopian tube, which is where the egg or zygote forms and from there, the cell divisions that we were talking about begin to be generated, which will make cellular embryo. Already in the fourth month of pregnancy all the organs are formed and the embryo stops being such to become a fetus that takes on human forms and will increase both in weight and size, and sexually differentiate into a man or woman.

At the same time, the pregnant mother will undergo a significant amount of changes in her body, in the digestive system she may feel heartburn, constipation, nausea, vomiting.
Her abdomen will increase in size as the pregnancy progresses.
She may also suffer from stretch marks, skin modification, and hemorrhoids from frequent constipation.

It is vital that during the whole process the death is medically controlled by specialized professionals such as the obstetrician and gynecologist, who will send you for ultrasound control studies to confirm that everything is going as corresponds.

Botany: sketch of the future plant that will flower

On the other hand, in the Botany, the embryo is called sketch of the future plant that is still inside the seed, it is something like a miniature plant in a dormant state of life.
The embryo is mainly the result of the fertilization of the oosphere, as the female gamete of spermatophytes, located in the embryo sac within the ovum and surrounded by two cells called synergists. The embryo will be made up of the radicle (part of the plant embryo that gives rise to the root), the hypocotyl (part of the plant that germinates from a seed), the cotyledons (the first leaves) and the geule (embryonic bud, gives rise to the stem and leaves of the plant adult).

Beginning of something

And also, in common language the job of the term embryo when you want to account or refer to incipient principle of a thing, question, or situation. ” The relationship between María and Juan is in an embryonic state.”
