    en.wikipedia.org/.../File:Seed_Development_Cycle.svg

    English: Seed development in plants consists of six stages: Stage I - Zygote Stage After double fertilization, the endosperm and zygote are visible. Stage II - Proembryo Stage The zygote divides to create a proembryo and a suspensor forms to transfer nutrients from the endosperm to the embryo allowing the embryo to grow.

    en.wikipedia.org/wiki/Seed_plant

    Runcaria has all of the qualities of seed plants except for a solid seed coat and a system to guide the pollen to the seed. [3] Runcaria was followed shortly after by plants with a more condensed cupule, such as Spermasporites and Moresnetia. Seed-bearing plants had diversified substantially by the Famennian, the last stage

  4. Seed - Wikipedia

    en.wikipedia.org/wiki/Seed

    The formation of the seed is the defining part of the process of reproduction in seed plants (spermatophytes). Other plants such as ferns, mosses and liverworts, do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates.

  5. Agricultural cycle - Wikipedia

    en.wikipedia.org/wiki/Agricultural_cycle

    The agricultural cycle is the annual cycle of activities related to the growth and harvest of a crop (plant). These activities include loosening the soil, seeding, special watering, moving plants when they grow bigger, and harvesting, among others. Without these activities, a crop cannot be grown.

  6. Plant development - Wikipedia

    From that point, it begins to divide to form a plant embryo through the process of embryogenesis. As this happens, the resulting cells will organize so that one end becomes the first root while the other end forms the tip of the shoot. In seed plants, the embryo will develop one or more "seed leaves" . By the end of embryogenesis, the young ...

    en.wikipedia.org/wiki/Evolution_of_photosynthesis

    A C3 plant uses the Calvin cycle for the initial steps that incorporate CO 2 into organic material. A C4 plant prefaces the Calvin cycle with reactions that incorporate CO 2 into four-carbon compounds. A CAM plant uses crassulacean acid metabolism, an adaptation for photosynthesis in arid conditions. C4 and CAM plants have special adaptations ...

  8. Vivipary - Wikipedia

    en.wikipedia.org/wiki/Vivipary

    Red mangrove seeds germinate while still on the parent tree. In plants, vivipary occurs when seeds or embryos begin to develop before they detach from the parent. Plants such as some Iridaceae and Agavoideae grow cormlets in the axils of their inflorescences. These fall and in favourable circumstances they have effectively a whole season's ...

  9. Vegetative reproduction - Wikipedia

    en.wikipedia.org/wiki/Vegetative_reproduction

    Plant propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual. It can happen through the use of vegetative parts of the plants, such as leaves, stems, and roots to produce new plants or through growth from specialized vegetative plant parts.
