    en.wikipedia.org/wiki/Flowering_plant

    Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (/ ˌ æ n dʒ i ə ˈ s p ər m iː /). [5] [6] The term 'angiosperm' is derived from the Greek words ἀγγεῖον / angeion ('container, vessel') and σπέρμα / sperma ('seed'), meaning that the seeds are enclosed within a fruit.

  3. Monocotyledon reproduction - Wikipedia

    en.wikipedia.org/wiki/Monocotyledon_reproduction

    The monocots (or monocotyledons) are one of the two major groups of flowering plants (or Angiosperms), the other being the dicots (or dicotyledons). In order to reproduce they utilize various strategies such as employing forms of asexual reproduction, restricting which individuals they are sexually compatible with, or influencing how they are ...

  4. Plant reproductive morphology - Wikipedia

    en.wikipedia.org/wiki/Plant_reproductive_morphology

    Close-up of a Schlumbergera flower, showing part of the gynoecium (specifically the stigma and part of the style) and the stamens that surround it. 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.

  5. ABC model of flower development - Wikipedia

    en.wikipedia.org/wiki/ABC_model_of_flower...

    ABC model of flower development guided by three groups of homeotic genes.. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower.

  6. Double fertilization - Wikipedia

    en.wikipedia.org/wiki/Double_fertilization

    The parts of a flower Double fertilization. Double fertilization or double fertilisation (see spelling differences) is a complex fertilization mechanism of angiosperms.This process involves the fusion of a female gametophyte or megagametophyte, also called the embryonic sac, with two male gametes (sperm).

  7. Plant reproduction - Wikipedia

    en.wikipedia.org/wiki/Plant_reproduction

    Asexual reproduction in plants occurs in two fundamental forms, vegetative reproduction and agamospermy. [1] Vegetative reproduction involves a vegetative piece of the original plant producing new individuals by budding, tillering, etc. and is distinguished from apomixis, which is a replacement of sexual reproduction, and in some cases involves ...

  8. Receptacle (botany) - Wikipedia

    en.wikipedia.org/wiki/Receptacle_(botany)

    Angiosperms The receptacle (grey) in relation to the ovary (red) in three types of flowers: hypogynous (I), perigynous (II), and epigynous (III) In angiosperms , the receptacle or torus (an older term is thalamus, as in Thalamiflorae ) is the thickened part of a stem (pedicel) from which the flower organs grow.

  9. Pseudogamy - Wikipedia

    en.wikipedia.org/wiki/Pseudogamy

    Apomixis in flowering plants (angiosperms) includes some types of vegetative reproduction and also agamospermy, which is asexual reproduction through seeds [9] (see apomixis for more information). Agamospermy can occur through many different mechanisms, [ 6 ] [ 7 ] some of which require pollination (pseudogamy), and some of which do not ...
