What is the Function of Sporangium

What is Sporangium

A sporangium is a structure found in plants and other species that is responsible for the production and storage of spores. Spores are haploid structures found in organisms that aid in germinating and the formation of new organisms. In other words, they aid in the reproduction of species.

What is Sporangiophores

Sporangia are structures that produce spores and are typically found on the lower surface of a thallus, but they can also be found on the upper surface and in other locations.  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. The sporangium develops on the sporangiophore and is composed of haploid nuclei and cytoplasm.

In the sporangiophore, spores are produced by encasing each haploid nucleus and cytoplasm in a tough outer membrane. These spores are spread by wind during asexual reproduction and germinate into haploid hyphae.

While sexual reproduction in fungi varies by phyla, the sporangium plays an indirect role in sexual reproduction in some fungi. Sexual reproduction occurs in Zygomycota when the haploid hyphae of two individuals unite to create a zygosporangium in response to unfavorable conditions.

Within the zygosporangium, the haploid nuclei fuse to form diploid nuclei. When the conditions change, the zygosporangium germinates, goes through meiosis, and develops into a sporangium, which releases spores.

In fern sporangia are borne on the top of a sporangiophore. The sporangia are exine, and the fern sporangia are anther-like, hence the name antherine. The ferns with sporoangia that are found on the sporophylls are known as discoid.

Acrogynum is a monotypic genus of flowering plants in the family Zingiberaceae, subfamily Acanthoideae. From the distribution of species and their fossil remains, this genus is placed in the family Acanthaceae.
“Acrogynum” is a vascular plant with a flowering stem and leaves. The stem is composed of a single pericycle with whorls of primary leaves. Pinnate leaves are present as well but are reduced or absent in some species.

Sporangium Diagram

The sporangium is a sac-like structure with some type of protoplast that is enclosed by a tough cell wall. This cell wall is designed to protect the spores and keep their DNA alive as long as possible. The cyst is a type of spore that has a tough outer coat.

Function of Sporangium

Sporangium is a type of sporophyte in which spores are produced.  It is found on the gametophyte plant and contains both male and female sex organs.  The spore-producing cells are called sporangia, hence the name “sporangium”

It is the spore-producing stage in the life cycle of many fungi, and can be found on various types of plants. The function of a sporangium is to produce spores

The sporangium is a compact structure that protects the spores, which are vital to the survival of the plant. The sporangium does this by containing the spores, which later release into soil. It also protects the spores from harsh weather conditions.

The structure of the sporangium can be found in many types of plants including mosses and liverworts.

The sporangium of liverworts is located in the upper, more mature part of the plant and is usually elliptical. The sporangium contains many spores called gemmae. These spores will germinate into new plants.

Sporangium and Sporophyte

Sporangium is a type of plant structure that produces spores.  The sporophyte is the sexual generation of plants, which develops from the spore.  A gametophyte is an organism that produces gametes (sex cells).

A sporangium can be found on the lower part of the stem. The spore is produced in a sac called an ascus, which becomes surrounded by a protective layer called an ascocarp or peridium.  The spores are released when it rains and they land on another plant’s leaves or soil.
