Embryo An embryo is an early stage of development of a multicellular diploid eukaryotic organism. In general, in organisms that reproduce sexually, an embryo develops from a zygote, the single cell resulting from the fertilization of the female egg cell by the male sperm cell. The zygote possesses half the DNA of each of its two parents.

Psychological development Psychological development. Psychological development, the development of human beings’ cognitive, emotional, intellectual, and social capabilities and functioning over the course of the life span, from infancy through old age. It is the subject matter of the discipline known as developmental psychology. Child psychology was the traditional focus of research, but since the mid-20th century much has been learned about infancy and adulthood as well. A brief treatment of psychological development follows. For full treatment, see human behaviour.

Developmental Psychology Developmental psychology, also referred to as human development, is the scientific and methodical study of systematic psychological changes that take place in human beings over the course of their life span. At first, the study of developmental psychology was only concerned with infants and children. But today, the field has grown to comprise of adolescence, adult development, aging, and the entire life span of an individual.

After that point in time, an embryo is called a fetus.

Ovum: Definition, Function & Structure Definition. All sexually reproducing organisms make sex cells called gametes. The gamete produced by the female is called the egg or ovum (plural = ova). It joins with the sperm, the male gamete, during fertilization to form the embryo, which will eventually grow into a new organism. Ova are produced by sexually reproducing animals, protists, fungi and flowering plants and ferns. In animals, they are produced by follicle cells in the ovaries of the female.

What Is a Plant Embryo? Plant embryology, or the development of a full-grown plant from an embryo, contains some elements of development that is seen in different types of animals. There is an egg and a sperm which unite to form the fledgling zygote. The seed-bearing organ of the plant is termed the pistil. It is there where the egg is located.

embryo All animals were embryos at one point: it's a very early stage of life. Another meaning is not as literal: the beginning of an idea could be called an embryo, as in, My plan for ice-skating robots is still in the embryo stage.. That means the idea isn't very developed. Definitions of embryo.

embryo The definition of an embryo is an unborn but developing child or animal, or something in the early stages that shows potential for development. 1  An example of an embryo is when you have a viable female human egg that has been fertilized with a man's sperm. An example of an embryo is the draft of a series of new laws protecting human rights that will be used in the development of a constitution to govern a country where a human rights violation is taking place.

The development of the human embryo? An ovum is fertilized in a fallopian tube through which it travels into the uterus. An embryo is called a fetus at a more advanced stage of development and up until birth or hatching. In humans, this is from the eighth week of gestation.

Developmental Psychology Developmental Psychology. Developmental psychology is a scientific approach which aims to explain how children and adults change over time. A significant proportion of theories within this discipline focus upon development during childhood, as this is the period during an individual's lifespan when the most change occurs.

Embryo …two major parts, endosperm and embryo. Endosperm is a starchy, storage tissue (popcorn is exploded endosperm). The embryo lies between the endosperm and fruit wall with the large scutellum facing the endosperm. The scutellum is thought to be a modified cotyledon, or seed leaf. In grasses this seed leaf never… Read More; bryophytes

- For other uses, see Embryo (disambiguation) . An embryo is a multicellular diploid eukaryote in its earliest stage of development, from the time of fertilization through sexual reproduction until birth, hatching, or germination.ome definitions consider embryological life to start at the third week of development to the eighth, when most organ systems are developing. The development of the embryo is called embryogenesis.

- Development is the process through which an embryo becomes an adult organism and eventually dies. Through development, an organism's genotype is expressed as a phenotype, exposing genes to the action of natural selection. Studies of development are important to evolutionary biology for several reasons:

- noun, plural fetuses. Embryology. 1. (used chiefly of viviparous mammals) the young of an animal in the womb or egg, especially in the later stages of development when the body structures are in the recognizable form of its kind, in humans after the end of the second month of gestation.

- The term ‘zygote’ comes from the root Greek word ‘zygotos’ meaning yoked or ‘to yoke’ or ‘joined’ or to ‘join’. On the other hand, embryo comes from the root Latin word ‘embryum’ meaning ‘that which grows’. Zygote is the first stage in the development process of an organism.

Embryo In humans, a pregnancy is generally considered to be in the embryonic stage of development between the fifth and the eleventh weeks after fertilization, and is expressed as a fetus from the twelfth week.

- In humans, an embryo is generally considered to be between the first and the eighth week of development after fertilization and from then it is instead called a fetus. Some definitions consider embryological life to start at the third week of development to the eighth, when most organ systems are developing.n humans, this is from the eighth week of gestation. However, animals which develop in eggs outside the mother's body are usually referred to as embryos throughout development; e.g. one would refer to a chick embryo, not a chick fetus even at late stages.

- In humans, the embryo refers to the growing organism after being a zygote and before being a fetus. The zygote becomes an embryo immediately after series of cell division. After the continuous cell division and differentiation in eight weeks, the embryo becomes a fetus in which the organism undergoes extensive organogenesis.
