sporangium

Examples of sporangium in the following topics:

• Fungi Reproduction

  • They may be released from the parent thallus, either outside or within a special reproductive sac called a sporangium.
  • Sporangiospores are produced in a sporangium .
  • This bright field light micrograph shows the release of spores from a sporangium at the end of a hypha called a sporangiophore.

• Bryophytes

  • The sporangium, the multicellular sexual reproductive structure, is present in bryophytes and absent in the majority of algae.

• Chytridiomycota: The Chytrids

  • Allomyces produces diploid or haploid flagellated zoospores in a sporangium.

• Protist Life Cycles and Habitats

  • This plasmodium is net-like and, upon maturation, forms a sporangium on top of a stalk.
  • The sporangium forms haploid spores through meiosis, after which the spores disseminate, germinate, and begin the life cycle anew.

• Sporophytes and Gametophytes in Seedless Plants

  • The sporophyte bears the sporangia (singular, sporangium): organs that first appeared in the land plants .

• Mosses

  • The seta (plural, setae) contains tubular cells that transfer nutrients from the base of the sporophyte (the foot) to the sporangium .

• Plant Adaptations to Life on Land

  • Four major adaptations are found in all terrestrial plants: the alternation of generations, a sporangium in which the spores are formed, a gametangium that produces haploid cells, and apical meristem tissue in roots and shoots.

• Liverworts and Hornworts

  • The liverwort's life cycle begins with the release of haploid spores from the sporangium that developed on the sporophyte.
