Meaning and Definition
The process of forming megaspores (large spores that develop into female gametophytes) within the ovule of a seed plant.
In botany, the specific phase of plant reproduction where a megaspore mother cell (megasporocyte) undergoes meiosis to produce (typically four) haploid megaspores, usually followed by the degeneration of three and the development of the remaining one into the female gametophyte (embryo sac).

Common Mistakes When Using “megasporogenesis”

- Confusing it with 'megagametogenesis' (development of the gametophyte *from* the megaspore).
- Using it outside a botanical context.
FAQ
Frequently Asked Questions
No. Megasporogenesis is the formation of megaspores via meiosis. Fertilisation is the later fusion of sperm and egg, which requires a developed female gametophyte from one of these megaspores.
It occurs in heterosporous plants, including all seed plants (gymnosperms and angiosperms) and some pteridophytes (like Selaginella).
The megaspore mother cell (or megasporocyte), a diploid cell within the ovule's nucellus that undergoes meiosis.
Although meiosis usually produces four haploid megaspores, in most flowering plants, three degenerate, leaving a single functional megaspore to develop into the female gametophyte.
The process of forming megaspores (large spores that develop into female gametophytes) within the ovule of a seed plant.
Megasporogenesis is usually technical/scientific (botany) in register.
Megasporogenesis: in British English it is pronounced /ˌmɛɡəˌspɔːrə(ʊ)ˈdʒɛnɪsɪs/, and in American English it is pronounced /ˌmɛɡəˌspɔːroʊˈdʒɛnəsɪs/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: MEGA (big) SPORE (reproductive cell) GENESIS (beginning). It's the 'big beginning' of the female reproductive cell in plants.
Conceptual Metaphor
A specialised production line: where a 'mother cell' (megasporocyte) in the 'factory' (ovule) undergoes a division process (meiosis) to create the raw material (megaspores) for building the female structure (gametophyte).
