Sporangium - Wikipedia
Sporangia can produce spores by mitosis, but in land plants and many fungi, sporangia produce genetically distinct haploid spores by meiosis. In some phyla of fungi, the sporangium plays a role in asexual reproduction, and may play an indirect role in sexual reproduction.
Sporangium – Definition, Characteristics, Structure, Importance
2024年3月29日 · Sporangium in Fungi. In the fungal kingdom, the sporangium is a pivotal structure, particularly in certain phyla, where it facilitates asexual reproduction and, in some instances, indirectly contributes to sexual reproduction. Located on the sporangiophore, the sporangium is a repository of haploid nuclei and cytoplasm.
Sporangium - Definition and Quiz - Biology Dictionary
2017年5月18日 · A sporangium (plural: sporangia) is the capsule structure belonging to many plants and fungi, in which the reproductive spores are produced and stored. All land plants undergo an alteration of generations to reproduce; the sporangium is borne upon the sporophyte, which is the asexual second generation structure.
Sporangium & Sporangiospores | Definition & Function - Lesson
2023年11月21日 · The sporangium is an essential structure in both fungi and land plants. It produces haploid spores through mitosis. It also contains these spores until they are mature to be released in the ...
Sporangium - an overview | ScienceDirect Topics
A sporangium is a small, stipitate (stalked) or nonstipitate (sessile) structure of restricted size (generally 1 mm in diameter) and definite shape, often roughly spherical, formed by the clumping of the plasmodium. From: Biodiversity of Fungi, 2004

2016年1月1日 · Parasitic nematodes can hitch a ride on the Pilobolus sporangium when it is squirted into the air and cause lung disease in mammals. Besides the carriage of spores inside animals (endozoochory), fungi are dispersed on the surface of their vectors (ectozoochory).

A sporangium is a small, stipitate (stalked) or nonstipitate (sessile) structure of restricted size (generally 1 mm in diameter) and definite shape, often roughly spherical, formed by the clumping of the plasmodium. In certain minute species (Echinosteliales) a plasmodium may …
Sporangium | biology | Britannica
…primitive fungi produce spores in sporangia, which are saclike sporophores whose entire cytoplasmic contents cleave into spores, called sporangiospores. Thus, they differ from more advanced fungi in that their asexual spores are endogenous. Sporangiospores are either naked and flagellated (zoospores) or walled and nonmotile (aplanospores).
Sporangium - Simple English Wikipedia, the free encyclopedia
Sporangia can produce asexual spores by mitosis, but in nearly all land plants and many fungi, sporangia are the site of meiosis, and produce genetically unique haploid spores. In flowering plants the sporangium tissue (except the epidermis) that produces the female spores is also called the nucellus .
What are sporangium and sporophyte? - BYJU'S
Sporangium is an enclosed capsule that contains spores produced in fungi and many more species. For most fungi to propagate and multiply, they produce and release spores. A mother cell is a reproductive unit that produces spores.
