  2. Katherine Esau - Wikipedia

    en.wikipedia.org/wiki/Katherine_Esau

    Esau was a pioneering plant anatomist and her books Plant Anatomy (1953) and Anatomy of Seed Plants (1960) are considered "iconic texts" in plant structural biology. [1] Her early work in plant anatomy focused on the effect of viruses on plants, specifically on plant tissue and development. Her doctoral research had changed from field to ...

    en.wikipedia.org/wiki/Plant_anatomy

    Chloroplasts in leaf cells of the moss Mnium stellare. Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.

  4. Plant morphology - Wikipedia

    en.wikipedia.org/wiki/Plant_morphology

    In seed plants, the embryo will develop one or more "seed leaves" . By the end of embryogenesis, the young plant will have all the parts necessary to begin in its life. Once the embryo germinates from its seed or parent plant, it begins to produce additional organs (leaves, stems, and roots) through the process of organogenesis.

    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

  6. Plant taxonomy - Wikipedia

    en.wikipedia.org/wiki/Plant_taxonomy

    The classification of plants results in an organized system for the naming and cataloging of future specimens, and ideally reflects scientific ideas about inter-relationships between plants. The set of rules and recommendations for formal botanical nomenclature, including plants, is governed by the International Code of Nomenclature for algae ...

    The remainder of the vascular plant sections address the higher plants (spermatophytes or seed plants, i.e. gymnosperms and angiosperms or flowering plants). In the higher plants, the terrestrial sporophyte has evolved specialised parts. In essence, they have a lower, underground component and an upper, aerial component.

  8. Calamopityaceae - Wikipedia

    en.wikipedia.org/wiki/Calamopityaceae

    Calamopityaceae is the largest family of the division of extinct seed-bearing plants (spermatophytes) known as Pteridospermatophyta. [1] [2] It is the only family in the monotypic order Calamopityales. [3] This family is characterized by its petioles and specific wood pattern, and it grew only in the Paleozoic era, specifically in North America ...

  9. 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.
