    en.wikipedia.org/wiki/Alternation_of_generations

    The entire gametophyte generation, with the sole exception of pollen grains (microgametophytes), is contained within the sporophyte. The life cycle of a dioecious flowering plant (angiosperm), the willow, has been outlined in some detail in an earlier section (A complex life cycle). The life cycle of a gymnosperm is similar.

  5. Flowering plant - Wikipedia

    en.wikipedia.org/wiki/Flowering_plant

    Angiosperm flower showing reproductive parts and life cycle. The characteristic feature of angiosperms is the flower. Its function is to ensure fertilization of the ovule and development of fruit containing seeds. [55] It may arise terminally on a shoot or from the axil of a leaf. [56]

  6. Double fertilization - Wikipedia

    en.wikipedia.org/wiki/Double_fertilization

    A far more rudimentary form of double fertilization occurs in the sexual reproduction of an order of gymnosperms commonly known as Gnetales. [3] Specifically, this event has been documented in both Ephedra and Gnetum, a subset of gnetophytes. [7] In Ephedra nevadensis, a single binucleate sperm cell is deposited into the egg cell. Following the ...

  7. ABC model of flower development - Wikipedia

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

    The transition from the vegetative phase to a reproductive phase involves a dramatic change in the plant's vital cycle, perhaps the most important one, as the process must be carried out correctly in order to guarantee that the plant produces descendants. This transition is characterised by the induction and development of the meristem of the ...

  8. Pollen tube - Wikipedia

    en.wikipedia.org/wiki/Pollen_tube

    Pollen tube elongation is an integral stage in the plant life cycle. The pollen tube acts as a conduit to transport the male gamete cells from the pollen grain—either from the stigma (in flowering plants) to the ovules at the base of the pistil or directly through ovule tissue in some gymnosperms.
