organogenesis
C2Scientific/Technical (Biology, Embryology, Medicine, Botany)
Definition
Meaning
The formation and development of organs in a living organism.
The process during embryonic development in which the three germ layers (ectoderm, mesoderm, endoderm) differentiate and arrange into specific organs and structures. In botany, it can refer to the differentiation of plant tissue into specific organs (e.g., leaves, flowers).
Linguistics
Semantic Notes
This is a process noun. The primary, default meaning is biological/embryological. It is a countable event/process (e.g., 'the organogenesis of the heart'). It is a hyponym (specific type) of 'morphogenesis'.

Examples
By Part of Speech
verb
British English
- The tissues begin to organogenise during the fifth week.
- Researchers observed the cells organogenising in vitro.
American English
- The tissues begin to organogenize during the fifth week.
- Researchers observed the cells organogenizing in vitro.
adverb
British English
- The cells developed organogenetically according to the model.
American English
- The cells developed organogenically according to the model.
adjective
British English
- The organogenetic stage is highly sensitive to teratogens.
- They studied the organogenetic potential of the cells.
American English

Examples
By CEFR Level
- This word is too advanced for A2 level.
- 'Organogenesis' is a scientific word about how body parts grow in a baby.
- Doctors study organogenesis to understand birth defects.
- During pregnancy, the period of organogenesis is when the baby's major organs are formed.
- Exposure to certain chemicals can disrupt normal organogenesis.
- The molecular pathways that orchestrate vertebrate organogenesis are remarkably conserved across species.
- His research focuses on the epigenetic regulation of cardiac organogenesis.
Learning
Memory Aids
Mnemonic
Think of 'ORGAN' + 'GENESIS' (beginning). It's the genesis (beginning/creation) of organs.
Conceptual Metaphor
DEVELOPMENT IS CONSTRUCTION/BUILDING (organs are 'built' during this phase).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'органогенез' (direct equivalent). The main trap is assuming a broader meaning; it's specifically about organ *formation*, not just any organ-related process.
- Avoid calquing as 'органо-генезис'; the established term is 'органогенез'.
Common Mistakes
- Misspelling as 'organogenisis'.
- Using it to refer to the function of organs (physiology) rather than their development.
- Pronouncing the 'g' in '-genesis' as a hard /g/ instead of /dʒ/.

FAQ
Frequently Asked Questions
No. Embryogenesis is the entire process of embryo development. Organogenesis is a specific phase within embryogenesis focused on organ formation.
In humans, the primary period of organogenesis is from about week 4 to week 8 of embryonic development (the embryonic period).
Yes, though less common. In botany, it can refer to the development of plant organs like leaves and flowers from meristematic tissue.
Both 'organogenetic' and 'organogenic' are accepted adjective forms, with 'organogenetic' being more common in British English.
