Definition of ovule in English:

ovule

noun ˈɒvjuːlˈəʊvjuːl

Botany

The part of the ovary of seed plants that contains the female germ cell and after fertilization becomes the seed.
Example sentencesExamples
- It is well known that most flowering plants produce more ovules than the number of seeds they mature.
- Once the pollen has fertilized the egg cell contained within the ovule, the ovule develops into a seed, and the ovary of the enclosing carpel begins to enlarge and ripen, forming the fruit.
- Distal flowers are often smaller and produce fewer or smaller ovules, seeds and fruits, but they may have higher pollen production.
- Relative to self-pollination, outcross pollination results in greater proportion of flowers setting fruit, and greater proportion of ovules yielding seeds per fruit.
- The number of pollen tubes and ovules in the ovaries of each of six dissected pistils from each cross is shown.
Synonyms
embryo, bud, nucleus, seed, spore, egg, ovum

ovular

adjective ˈɒvjʊləˈəʊvjʊlə

Botany

Nevertheless, there is a consensus that the palisade layer, which develops from the outer epidermis of the outer ovular integument, is critical in determining the permeability property of a seed coat.
Example sentencesExamples
- With advances in molecular biology, lines with fuzzless and fiberless seed phenotypes have become very important in determining differences in gene/protein regulation during development of ovular trichomes.
- These filial organs are enclosed by a maternal seed coat, derived from one or both ovular integuments.
- However, any role of ethylene, produced due to damaging the ovular base, cannot be excluded.

Origin

Early 19th century: from French, from medieval Latin ovulum, diminutive of ovum.
