Definition of ovule in English:



  • The part of the ovary of seed plants that contains the female germ cell and after fertilization becomes the seed.

    • ‘The number of pollen tubes and ovules in the ovaries of each of six dissected pistils from each cross is shown.’
    • ‘It is well known that most flowering plants produce more ovules than the number of seeds they mature.’
    • ‘Relative to self-pollination, outcross pollination results in greater proportion of flowers setting fruit, and greater proportion of ovules yielding seeds per fruit.’
    • ‘Distal flowers are often smaller and produce fewer or smaller ovules, seeds and fruits, but they may have higher pollen production.’
    • ‘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.’
