Past gastrulation, an embryo continues to develop into a mature multicellular organism by forming structures necessary for life outside of the womb or egg. As the name suggests, organogenesis is the stage of embryonic development when organs form.

What is develops into an embryo?
The fertilized egg (zygote) divides repeatedly as it moves down the fallopian tube to the uterus. First, the zygote becomes a solid ball of cells. Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes.
What is embryo and when it develops?
An embryo is the early stage of human development in which organs are critical body structures are formed. An embryo is termed a fetus beginning in the 11th week of pregnancy, which is the 9th week of development after fertilization of the egg. A zygote is a single-celled organism resulting from a fertilized egg.
What is embryo in biology?
Embryo: An organism in the early stages of growth and differentiation, from fertilization to the beginning of the third month of pregnancy (in humans). After that point in time, an embryo is called a fetus.
What is an embryo of a seed?
The embryo is the young multicellular organism before it emerges from the seed. The seed coat consists of one or more protective layers that encase the seed. A seed begins to form an embryo following fertilization and the start of a zygote. The initial division of the zygote results in two cells.
What is a blastocyst embryo?
Three days after fertilization, a normally developing embryo will contain about six to 10 cells. By the fifth or sixth day, the fertilized egg is known as a blastocyst — a rapidly dividing ball of cells. The inner group of cells will become the embryo.
How is embryo formed in plants?
Embryogenesis occurs naturally as a result of single, or double fertilization, of the ovule, giving rise to two distinct structures: the plant embryo and the endosperm which go on to develop into a seed. The zygote goes through various cellular differentiations and divisions in order to produce a mature embryo.
What happens during the embryonic stage?
The embryonic stage plays an important role in the development of the brain. Approximately four weeks after conception, the neural tube forms. This tube will later develop into the central nervous system including the spinal cord and brain. The neural tube begins to form along with an area known as the neural plate.
How is an embryo developed for Class 8?
1) The zygote divides repeatedly to make a ball of hundreds of cells. This is called an embryo. The embryo moves down the oviduct into the uterus. 3)The cells of embryo begin to form specialised groups that develop into different tissues and organ of the baby.
What does a blastocyst develop from?
blastocyst, a distinctive stage of a mammalian embryo. It is a form of blastula that develops from a berrylike cluster of cells, the morula. A cavity appears in the morula between the cells of the inner cell mass and the enveloping layer. This cavity becomes filled with fluid.
What is implantation in biology?
Implantation is a process in which a developing embryo, moving as a blastocyst through a uterus, makes contact with the uterine wall and remains attached to it until birth.
What is embryo in simple terms?
1: an unborn human or animal in the earliest stages of growth when its basic structures are being formed. 2: a tiny young plant inside a seed. embryo.
What is embryo function?
An embryo is the early stage of development of a multicellular organism. In general, in organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization and continues through the formation of body structures, such as tissues and organs.
Where do plant embryos develop?
Most of the plant embryo develops from the apical (terminal) cell. The suspensor develops from the basal cell. The suspensor anchors the embryo to the endosperm and serves as a nutrient conduit for the developing embryo. Further cell division leads to the globular stage.
What does the plumule of the embryo refer to?
The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumule does not occur until the cotyledons have grown above ground.
