embryogenesis
Definition
Embryogenesis (noun): The process by which an embryo develops from a fertilized egg (zygote) into a multicellular organism. It encompasses the stages of cell division, differentiation, and morphogenesis that lead to the formation of tissues, organs, and body structures.
Usage Examples
- (The developmental process starts right after the egg is fertilized.)
- (Examining how embryos form can reveal causes of congenital abnormalities.)
- (The development of the plant embryo takes place inside the seed.)
Advanced Usage
"Early embryogenesis": The initial stages of embryonic development, particularly cleavage and blastula formation.
- Mutations during early embryogenesis can lead to severe developmental disorders. (Genetic changes in the first cell divisions may cause major problems.)
"Embryogenesis in vitro": The development of an embryo outside the living organism, often in a laboratory setting.
- Scientists study embryogenesis in vitro to observe cell differentiation under controlled conditions. (Researchers watch embryo growth in a dish to analyze cellular changes.)
Variants and Related Words
Embryogenic (adj): relating to or capable of producing an embryo.
- Embryogenic cells are used in plant tissue culture to generate new plants. (Cells that can form embryos are employed to grow plants.)
Embryo (n): an early stage of development of a multicellular organism.
- The embryo is protected by the amniotic sac during embryogenesis. (The developing organism is safeguarded inside a fluid-filled membrane.)
Synonyms
- Embryonic development: the process of an embryo forming and growing.
- Organogenesis (more specific): the stage of embryogenesis where organs form.
Related Idioms
- "In the embryonic stage": at an early, undeveloped phase.
- The project is still in the embryonic stage of development. (The project is just beginning to take shape.)
Phrasal Verbs
- Carry out embryogenesis: to undergo or perform the process of embryonic development.
- The fertilized egg carries out embryogenesis within the mother's womb. (The zygote undergoes development inside the uterus.)
