  2. The sporangium is borne on a stalk known as the sporangiophore. (Web site)
  3. In fungi, a sporangium is produced at the end of a sporangiophore that sheds spores. (Web site)

  3. Another interesting adaptation of Pilobolus is that the sporangium is covered in calcium oxalate crystals.

Vesicle

  1. Its spore-bearing structures consist of an erect hypha (sporangiophore) which is swellen into a vesicle below the sporangium.

  2. Spherical sporangiospores are seen within the sporangium and around the columella (a dome-shaped structure located at the top end of the sporangiophore).
  3. Sporangiophore: A specialized hypha that bears a sporangium. (Web site)

Fungus

  1. Using a mucus-like substance found in the vesicle of the fungus, the sporangium can adhere itself onto whatever it lands., thus completing its life cycle. (Web site)

Mycelium

  1. Once outside its host, spores within the sporangium germinate and grow as a mycelium within the excrement, where it is a primary colonizer. (Web site)

Structure

  1. Asexual reproduction occurs in most Oomycetes by the formation of a structure called a sporangium (pl.
  2. A sporangium generally has a central columella (structure g), which may extend and be visible below the sporangium as a swelling known as the apophysis.

Ascus

  1. Thallus septate; spores developed in special type of sporangium, the ascus, the number of spores being usually eight. (Web site)
  2. Furthermore, the morphology and development of the sexual sporangium of the fission yeasts is similar to the ascus of other ascomycetes (4, 5). (Web site)

Water

  1. Pith tissue incubated in water induces formation of a sporangium. (Web site)

Enclosed

  1. Spores are enclosed within a capsule (sporangium) and are produced in groups of four (tetrads) when the parent cell divides meiotically.
  2. A sporangium of Syzygites megalocarpus with the spores (yellow) still enclosed in the sporangial wall.

Zygospore

  1. Subsequently, the zygospore germinates and forms a sporangiophore whose sporangium contains both + and - haploid spores. (Web site)

Germination

  1. Spore formation takes place after germination of the zygospore in the sporangium.

End

  1. Sporangiospores are produced in sporangium (sac) at the end of an aerial hypha (sporangiophore) c. (Web site)
  2. Germination begins when the diploid nucleus undergoes meiosis and a sporangium develops at the end of a germ tube. (Web site)

Zoospores

  1. They germinate either directly by a germ tube with or without a sporangium on the end, or indirectly by the formation of a vesicle with zoospores.
  2. Zoospores just in the process of releasing from a sporangium. (Web site)
  3. In Aphanomyces and species of Phytophthora, differentiation of zoospores occurs in the sporangium.

Chytrids

  1. Chytrids develop a structure called a sporangium that has motile spores equipped with a posterior flagellum, a long, whiplike tail that aids in locomotion. (Web site)
  2. Chytrids: Zoosporic fungi can only disperse in water LINK. The zoospore requires at least a film of water to move away from the sporangium. (Web site)

  2. The sporophyte produces a single sporangium that is raised above the substrate. (Web site)

Hypha

Sporangium

  1. When the environment is favorable, the zygospore germinates, meiosis occurs, and a sporangium is produced at the end of a sporangiophore. (Web site)
  2. Sporangiospores: spores produced by a sporangium in many fungi such as zygomycetes. (Web site)
