Core angiosperms. The flowering plants , also known as angiosperms , Angiospermae [5] [6] or Magnoliophyta , [7] are the most diverse group of land plants , with 64 orders , families , approximately 13, known genera and , known species. However, they are distinguished from gymnosperms by characteristics including flowers , endosperm within the seeds , and the production of fruits that contain the seeds.

The angiosperm carpel is one of the defining characteristics of flowering plants. Carpels are unique to angiosperms and are found in all of its members. Yet, due to the distinctive structure and function of carpels, deducing homologies among carpels and other seed-plant organs has been difficult. Progress in understanding carpel homologies and evolution is being made in a number of directions. Homologies, as well as transformations between them, have been proposed among angiosperms and other seed plants. These include homologies among the reproductive structures of Glossopterids, Caytonia , and other fossil taxa e. Recent studies have examined the homologies and transformations among female reproductive organs through outgroup comparison e.



  1. Kr9 says:

    Growing evidence of morphological diversity in angiosperm flowers, seeds and pollen from the mid Cretaceous and the presence of derived lineages from increasingly older geological deposits both imply that the timing of early angiosperm cladogenesis is older than fossil-based estimates have indicated.
