  2. Plant reproductive morphology - Wikipedia

    en.wikipedia.org/wiki/Plant_reproductive_morphology

    Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers , which are the reproductive structures of angiosperms , are the most varied physically and show a correspondingly great diversity ...

  3. Plant reproduction - Wikipedia

    en.wikipedia.org/wiki/Plant_reproduction

    Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes , resulting in offspring genetically different from either parent.

  4. Gynoecium - Wikipedia

    en.wikipedia.org/wiki/Gynoecium

    [note 1] A carpel is the female reproductive part of the flower—usually composed of the style, and stigma (sometimes having its individual ovary, and sometimes connecting to a shared basal ovary) —and usually interpreted as modified leaves that bear structures called ovules, inside which egg cells ultimately form. A pistil may consist of ...

  5. Sexual reproduction - Wikipedia

    en.wikipedia.org/wiki/Sexual_reproduction

    They are small plants found growing in moist locations and like ferns, have motile sperm with flagella and need water to facilitate sexual reproduction. These plants start as a haploid spore that grows into the dominant gametophyte form, which is a multicellular haploid body with leaf-like structures that photosynthesize. Haploid gametes are ...

  6. Sex organ - Wikipedia

    en.wikipedia.org/wiki/Sex_organ

    In plants, male reproductive structures include stamens in flowering plants, which produce pollen. [3] Female reproductive structures, such as pistils in flowering plants, produce ovules and receive pollen for fertilization. [4] Mosses, ferns, and some similar plants have gametangia for reproductive organs, which are part of the gametophyte. [5]

  7. Sexual system - Wikipedia

    en.wikipedia.org/wiki/Sexual_system

    a sexual system for plants when female, hermaphrodite, and gynomonoecious plants coexist in the same population. [24]: 360 Monoicy: one of the main sexual systems in bryophytes. [17] In monoicy male and female sex organs are present in the same gametophyte. [18] Monoecy: a sexual system in which male and female flowers are present on the same ...

  8. Ovule - Wikipedia

    en.wikipedia.org/wiki/Ovule

    Location of ovules inside a Helleborus foetidus flower. In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the integument, forming its outer layer, the nucellus (or remnant of the megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center.

    Stigma of a Tulipa species, with pollen Closeup of stigma surrounded by stamens of Lilium 'Stargazer'). The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant.
