A sporangium (from Late Latin, from Ancient Greek σπορά (sporá) 'seed' and ἀγγεῖον (angeîon) 'vessel'); pl.: sporangia) [1] is an enclosure in which spores are formed. [2] It can be composed of a single cell or can be multicellular .

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.

2025年1月30日 · In mosses, sporangia are located at the tips of the stalks. These stalks rise above the leafy part of the moss. The sporangia in mosses are often capsule-shaped. They release spores when they mature. Ferns have sporangia on the underside of their leaves. These leaves are often called fronds. The sporangia are grouped together in clusters known ...

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).

2024年3月29日 · Sporangia are specialized structures in plants responsible for the production and dispersal of spores. Their organization, position, shape, and source can vary, leading to different classifications. Here’s an in-depth look at the various types of sporangia:

A sporangium (pl: sporangia) [1] [2] is an enclosure in which spores are formed. [3] It can be a single cell or multicellular. All plants, fungi, and many other lineages form sporangia at some point in their life cycle.

2025年1月12日 · Sporangia exhibit diverse forms and functions across plant and fungal groups, adapting to different environmental conditions and reproductive strategies. Each type of sporangium has unique characteristics that enable it to fulfill its role in species propagation.

In the male stobilus or microstrobilus, the sporophylls are called micosporophylls and the sporangia, microsporangia, which produce the pollen. In most microstrobili, the microsporangia are located on the abaxial (under) side of the micosporophylls.

In vascular plants, whether the structure is a cone, fertile leaf, or flower-all are clusters of sporangia. The evolution of morphologically distinct sporangia (heterospory) and retention of the gametophyte evolved three times independently as a prerequisite for the evolution of seeds.

2023年10月26日 · Sporangia are the structures that enclose spores. they can be either unicellular or multicellular. Therefore, there are two types of sporangia: unilocular sporangia and plurilocular sporangia. Unilocular sporangia are a type of sporangia produced by brown algae, Ectocarpus.
