closed sac-like structure in which asexual spores (sporangiospores)are formed. The sporangium is borne on a stalk known as the sporangiophore.

a saclike structure, the entire protoplasmic contents of which become converted into an indefinite number of spores. See also zoosporangium and zoospores. Tinsel flagellum - a flagellum that bears hairs (mastigonemes) on the flagellar membrane.

A general term used in fungi to describe a structure containing spores. It is used for the small fruitbodies (uniform in size) produced by slime moulds. It is also applied to the tiny fruitbodies of fungi such as the bread mould ( Rhizopus) in the division Zygomycota.

the part the produces spores.

(spor an´ gee um) [Gr. spora: seed + angeion: vessel or reservoir] • In plants and fungi, any specialized stucture within which one or more spores are formed.

Structures on a plant that are responsible for producing and releasing spores. The powdery yellow-orange spots on the underside of a bracken leaf are sporangia, releasing haploid spores that will germinate into the gametophyte generation of the plant.

Spore producing organ on the underside of the fronds of all ferns.

A case holding spores. Plural = sporangia

organ containing or producing spores

a capsule that produces spores called sporangiospores

a spore -case or a receptacle for spores

a structure that produces spores (see the diagram of an ovule below)

A case or container for spores (plural=sporangia).

A single-celled or many-celled structure in which spores are produced, as in fungi, algae, mosses, and ferns. Also called spore case.

One-cell thick spore casing.

(pl. sporangia) A capsule in fungi and plants in which meiosis occurs and haploid spores develop.

Spore-producing structure on a sporophyte. In heterosporous plants, two types of sporangia are produced: megasporangia and microsporangia.

(pl. Sporangia) - A fruiting body that produces asexual spores within a more or less spherical wall.

(pl. sporangia) A chamber inside of which spores are produced through meiosis.

a structure within which spores are formed. pl. sporangia.

(Pl. sporangia) a type of fruiting body formed when a plasmodium breaks up into a number of small portions.

the reproductive organ of primitive plants like ferns and mosses

Specialized cell containing sporangiospores

Plural: sporangia. The roughly spherical structures which produce spores on the surface of fern fronds. When the sporangia are mature they open to release the spores. Usually several to many sporangia are attached near one another in conspicuous clusters. These clusters of sporangia are known as sori.

A structure within which spores are produced.

A fungal structure producing asexual spores, usually zoospores.

A sac that bears endogenous, asexual spores (sporangiospores) (Pl. sporangia.) ( 15)

a sac-like structure in which the cytoplasm is divided by walls to form one to many (usually thousands of ) spores.

An asexual sac-like cell that has its entire content cleaved into sporangiospores.

A sporangium (pl., sporangia) is a plant or fungal structure producing and containing spores. Sporangia occur on angiosperms, gymnosperms, ferns, fern allies, mosses, algae, and fungi.
