My Flashcards

Definition

Meaning

The production of seeds without fertilisation, involving asexual reproductive processes within the ovule.

A botanical term for a form of asexual reproduction (apomixis) in flowering plants where seeds are produced without the fusion of male and female gametes, resulting in offspring genetically identical to the parent plant.

Linguistics

Semantic Notes

A specialised term used almost exclusively in botany and plant genetics. It is a subset of apomixis, specifically referring to seed development without fertilisation, distinct from vegetative propagation.

Examples

By Part of Speech

verb

British English

  • The dandelion population largely reproduces by agamospermising, maintaining its genetic profile.

American English

  • This citrus variety can agamospermize, producing true-to-type seeds without pollination.

Examples

By CEFR Level

A2
  • Agamospermy is a difficult word about plants.
B1
  • Some plants can make seeds without sex, a process called agamospermy.

Learning

Memory Aids

Mnemonic

Imagine a plant that says, "A-GAME-O'-SPERM? Not for me!" (A-gamos-permy), meaning it doesn't need sperm/gametes to play the seed-making game.

Conceptual Metaphor

CLONING AS SEED PRODUCTION (The plant 'clones' itself by packaging an embryo into a seed without sexual partnership).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not confuse with 'партеногенез' (parthenogenesis), which is embryo development from an unfertilised egg, often in animals. Agamospermy is specifically seed-based.
  • The '-spermy' part relates to 'seed' (sperma), not directly to 'sperm' (сперматозоид).

Common Mistakes

  • Misspelling as 'agamosperm' or 'agamospemy'.
  • Using it as a general synonym for all asexual reproduction in plants.
  • Incorrect pronunciation placing stress on the first syllable (/ˈæɡəməʊspɜːmi/).

FAQ

Frequently Asked Questions

No. Vegetative propagation involves new plants growing from stems, roots, or leaves (e.g., runners, tubers). Agamospermy specifically produces a new individual from a seed that developed without fertilisation.

No. Agamospermy is a botanical term for seed-based asexual reproduction, which is a structure unique to plants. A similar concept in some animals is parthenogenesis.

It allows a well-adapted plant to produce genetically identical offspring (clones) via seeds, ensuring successful traits are preserved and allowing seed dispersal, without needing pollinators or compatible mates.

It is rare in major crops but is a subject of intense research. Introducing agamospermy into crops like maize or wheat could allow farmers to save seeds from high-yielding hybrids without losing their superior traits.
