Characteristics of Gymnosperms

May 13, 2024 | by Bloom Code Studio

  • The gymnosperm is a woody plant with seeds on the inner side of scale leaves that are usually arranged spirally to form cones or strobili but without flowers.
  • Intermediated group between Cryptogams and Angiosperms.
  • As gymnosperm lacks an ovary, it can’t produce fruit.
  • They are perennial and show extreme xerophytic and terrestrial adaptation but never aquatic.
  • In the steam and root, secondary growth occurs.
  • Seeds present in a gymnosperm are naked that develop from ovules.
  • Generally, gymnosperms are polyembryony, oospore forms embryo.
  • Sexual reproduction is of oogamous type.
  • They have formed male and female cones that bear microsporophylls on which microsporangia are born and megasporophylls on which megasporangia are born, respectively. 
  •  Endosperm (of seeds) helps in the storage of food for the development of the plant.
  • They are the dominant vegetation where snow is the source of water rather than water ( i.e, in cold regions of the world).
  • The wind is a significant source of pollination.
  • The gymnosperms are unisexual and may be monoecious or dioecious.
  • Absence of double fertilization and triple fertilization.
  • There is a lack of colorful sepals and petals in their reproductive organs.
  • At the end of the suspensor, the embryo is fully developed.
