What is the function of Sporangiophores?
The spore-producing cells within sporangia are called sporangiophores. When mature, sporangia release their spores through an opening or pore. The sporangium is involved in asexual reproduction and can play an indirect role in sexual reproduction in certain fungi phyla.
What is the meaning of sporophytic?
Definition of sporophyte : the diploid multicellular individual or generation of a plant with alternation of generations that begins from a diploid zygote and produces haploid spores by meiotic division — compare gametophyte.
What is the difference between Sporangiophore and Conidiophore?
The key difference between conidiophore and sporangiophore is that conidiophore is the aerial hypha of ascomycetes fungi that bears asexual spores called conidia while sporangiophore is the aerial hypha of zygomycetes fungi that bears asexual spores called sporangiospores.
What is the example of Sporangiospores?
The spore produced and contained within a sporangium. Sporangiospores occur in angiospersms, gymnosperms, ferns, fern allies, bryophytes, algae, and fungi.
How sporangia are formed?
The sporangium forms on the sporangiophore and contains haploid nuclei and cytoplasm. Spores are formed in the sporangiophore by encasing each haploid nucleus and cytoplasm in a tough outer membrane. During asexual reproduction, these spores are dispersed via wind and germinate into haploid hyphae.
Is sporangium for male or female?
In homosporous organisms there exists only one kind of sporangium, and in heterosporous organisms there exists two: a male sporangium is called a microsporangium and a female is called a megasporangium.
What are the two types of Sporangiospores?
Sporangiospores are either naked and flagellated (zoospores) or walled and nonmotile (aplanospores). The more primitive aquatic and terrestrial fungi tend to produce zoospores.
Where are Sporangiospores produced?
sporangium
Sporangiospores are spores that are produced in a sporangium (plural: sporangia). A sporangium in fungi (but not mosses and some other organisms) is simply a cell containing spores.
Where are sporangia formed?
The sporangia (spore cases) occur singly on the adaxial side (the upper side facing the stem) of the leaf. The lycophytes generally bear conelike structures called strobili, which are tight aggregations of sporophylls (sporangium-bearing leaves).
How does a sporangium work?
Sporangia are the structures that house and create spores in certain organisms. As many of these organisms are non-mobile, they have no choice but to release the spores out into the environment. This allows the spores, which are haploid, the opportunity to germinate and form gametophytes.
What’s the difference between Sporangiophore and Conidiophore?
How is leptosporangium developed from a single cell?
Leptosporangium is developed from a single initial cell. Sporangial initial undergo a periclinal division to form an outer layer and an inner layer of cells. Sporangial initial undergo a periclinal division to form an outer cell and inner cell.
What is leptosporangiate development?
Leptosporangiate development is present only in some advanced Pteridophytes (members of Leptosporangiopsida called true ferns). Eusporangia occurs either singly or on specialized sporophylls which aggregated to form a cone or strobilus.
What is the difference between leptosporangium and sporangium?
Leptosporangium is developed from a single initial cell. Sporangial initial undergo a periclinal division to form an outer layer and an inner layer of cells. Sporangial initial undergo a periclinal division to form an outer cell and inner cell. The outer layer of cells produces the sporangial wall.
What do eusporangia and leptosporangia have in common?
Ø Both Eusporangia and Leptosporangia are the spore producing structures in vascular plants. Ø Both are formed on the sporophyll (a specialized leaf) of the diploid sporophytic plant. Ø Both produce haploid spores after meiosis.
