The first rudiments of an organism, whether animal or plant
The young of an animal in the womb, or more specifically, before its parts are developed and it becomes a fetus (see Fetus).
The germ of the plant, which is inclosed in the seed and which is developed by germination.
Pertaining to an embryo; rudimentary; undeveloped; as, an embryo bud.
Portion of seed that produces a seedling.
a term used to describe a child in the womb from fertilization to 8 weeks following fertilization
Unborn baby from 2 to 8 weeks after it is formed
A salmon in its first growing stages before it is born out of its egg.
The developmental stage beginning at fertilization and ending at the start of the third developmental month.
a young animal or living thing.
An animal or plant in the earliest stages of development.

The early stage of development of a mammal (in the uterus), or a bird (in the shell).
The term used to describe the early stages of fetal growth. Strictly defined from the second to the ninth week of pregnancy, but often used to designate any time after conception.
A young plant enclosed in a seed
the developing human organism that arises from the entocyst disc of the conceptus, from the 3rd week until the 8th week of gestation.
A fertilized egg that has begun cell division, often called a pre-embryo. An embryo is now defined as a later stage, i.e. at the completion of the pre-embryonic stage which is considered to end at about day 14.
1) the beginning of any organism in the early stages of development, 2) a stage (between the ovum and the fetus) in the prenatal development of a mammal, 3) in humans, the stage of development between the second and eighth weeks following fertilization, inclusive.
the fetus is first called an embryo during the first eight weeks after conception.
The young plant that is present in a seed before germination.
Refers to a human organism during the first fifty-six days of its development following fertilization or creation, excluding any time in which its development has been suspended (eg. frozen).
an early stage in the development of an animal. The embryo is contained in either an egg, egg membranes, or the mother. The human embryo develops into a fetus.
The rudimentary plant contained in a seed. It consists of radicle and plumule and one or more cotyledons
an organism in the early stagesof development. In plants, the immature plant that develops within the seed.
a non-free-living multicellular body
A unique boy or girl produced by natural human reproduction or artificial reproductive methods such as cloning.
Stage in the developing mammal at which the characteristic organs and organ systems are being formed: for humans, this involves the stages of development from the second to the eighth week (inclusive post conception) In birds, the stage of development from the fertilization of the ovum up to hatching In plants, the stage of development within the seed
the name given to the fertilized egg from implantation through the eighth week of pregnancy
An embryo is the fertilized ovum shortly after fertilization up until eight weeks gestation.
A baby animal before it is hatched or born. A fertilized egg in the early stages of development prior to hatching.
The structure within a seed that develops into a plant.
An organism in early development, following fertilisation and before the formation of major organs.
The early stage of development of a fertilised egg.
for purposes of the proposed legislation A human organism during the first 56 days of its development following fertilization or creation, excluding any time in which its development has been suspended, and includes any cell derived from an embryo and used for the purpose of creating a human being.
Once a zygote begins to undergo cellular divisions, it becomes an embryo.
the early developmental stage of an organism produced from a fertilized egg.
1. the stage of multicellular organism that develops form a zygote before it becomes free-living. 2. specifically, in vertebrates, the period from after the long axis appears until all major structures are represented. In humans, this from about two weeks after fertilization to the end of the seventh or eighth week (Morris 1992).
the early stages of development in an organism
the young of any organism in an early stage of development; in humans, the developing organism from fertilization to the end of the eighth week in utero
A rudimentary plant in the seed.
Name given to a baby in the first 8 weeks of development in the womb.
The medical term for the developing cells during the first eight weeks of pregnancy. If the pregnancy continues, these cells will later become a baby.
an organism in the earlier stages of its development. For zebra mussels, this might refer to the developing zebra mussel prior to development of the velum, a larval organ of feeding and locomotion, at about 2 - 4 days after fertilization.
A fertilized egg. In humans, the fertilized egg is usually called an embryo from the time the egg is fertilized until the eighth week of development.
In humans the embryonic period spans the first eight weeks of development. It results in a recognisable human being though with a large head and a small body.
a period during pregnancy where the baby has rapid growth, and the main external features begin to take form.
Name for developing baby in first 10 weeks of pregnancy.
A fertilized egg that has undergone one or more divisions.
Stage of development in ontogeny of an organism between a zygote (fertilized egg) and juvenile. In amniotes, associated with an amnion and (in cases of oviparous amniotes) an egg.
the early developmental stage of an animal, while it is in the egg or uterus of the mother. In humans, the term is applied to unborn children up to the end of the seventh week after conception.
The unborn human organism from the second to about the eighth week of pregnancy.
An organism before birth, hatching or germination (in plants only). This covers the development of the organism from the new cell formed by the fusion of two gametes in sexual reproduction (the zygote) until the time the new organism has independent existence.
The product of the fusion of an egg and a sperm at conception. This term is reserved for the first eight weeks of development.
Stage of development of a human baby starting at the beginning of the 2nd week until the end of the 8th week.
An early stage in the post-fertilization development of an animal or plant egg.
The structure that develops from the zygote.
organism in early stages of development, before it is physiologically independent.
an animal in the earliest stages of its development in the uterus or the egg, specifically, in humans, from conception to about the eighth week.
The name for a developing baby during the first eight weeks after conception.
An organism in the early stages of development. In humans, this may refer to the period between the 3rd cell division of the fertilized egg and the point when the body shape is essentially formed (generally the beginning of the third month of pregnancy). Compare with "pre-embryo."
The fertilized ovum from shortly after the time of fertilization until eight weeks of gestation
The word is used loosely to describe everything from a fertilised egg (or zygote) to a fetus, including the embryo. What nowadays we call the embryo has for long been called the ovum by professional embryologists.
(EHM-bree-o) In the human, it is the developing organism during its first eight weeks of life following fertilization.
The stage of growth of a fertilized egg from implantation in the uterus, which starts 7 - 8 days after ovulation and is complete after further 5 days, until the end of the eighth week of pregnancy. This period involves rapid growth and development of the major organ systems and main external features.
When a pre-embryo (zygote) grows and gets to be a certain size and sticks itself to the inside of the uterus it becomes an EMBRYO. It takes eight weeks after fertilization for the EMBRYO to grow into a fetus.
The rudimentary plant present in the seed; composed of the embryonic axis (shoot end and root end) and the scutellum
The early stage of development of the young of any organism. In humans the embryonic period is from about 2 to 8 weeks' gestation and is characterized by cellular differentiation and predominantly hyperplastic growth.
The name given to a developing infant from about two weeks after conception to the end of the second month of pregnancy, when it is then called a foetus.
