How to use sporogenous in a sentence? Find typical usage patterns (collocations)/phrases/context for "sporogenous" and check conjugation/comparative form for "sporogenous". Mastering all the usages of "sporogenous" from sentence examples published by news publications.
The fertile sporogenous cells are surrounded by layers of sterile cells that grow into the wall of the pollen sac. Some of the cells grow into nutritive cells that supply nutrition for the microspores that form by meiotic division from the sporogenous cells. In a process called microsporogenesis, four haploid microspores are produced from each diploid sporogenous cell (microsporocyte, pollen mother cell or meiocyte), after meiotic division. After the formation of the four microspores, which are contained by callose walls, the development of the pollen grain walls begins.

Corn pollen grains are large, about 90–100 µm. Most grass pollen is around 20-25 µm. In angiosperms, during flower development the anther is composed of a mass of cells that appear undifferentiated, except for a partially differentiated dermis. As the flower develops, four groups of sporogenous cells form within the anther.

The gleba of the "common earthball" (Scleroderma citrinum) has a dark color. Gleba is the spore-bearing inner mass of certain fungi such as the puffball or stinkhorn. The gleba is a solid mass of spores, generated within an enclosed area within the sporocarp. The continuous maturity of the sporogenous cells leave the spores behind as a powdery mass that can be easily blown away.

Arthrographis kalrae is primarily known as an asexual fungus, producing single-celled arthroconidia with thin, smooth walls. The fungus grows relatively slowly culture with colonies initially yellowish-white in colour and yeast-like, varying from yellowish-brown to tan in color and powdery at maturity. Most sporogenous hyphae are irregularly branched in a tree-like pattern at the apex. Diversity in colonial morphology does not appear to correlate with genotypic diversity.

The male reproductive organs generally develop more rapidly and appear sooner than the female organs. The male organs contain microsporangia which divide to form sporogenous tissue, composed of cells which become archesporial cells. These develop into microspores, or pollen-mother cells, once they are rounded and filled with starch grains. When the microspores undergo meiosis in the spring, four haploid microspores are produced which eventually become pollen grains.

The Mixiomycetes are class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. The class contains a single order, the Mixiales, which in turn contains a single family, the Mixiaceae that circumscribes the monotypic genus Mixia. Only one species has been described to date, Mixia osmundae; this species was originally named Taphrina osmundae by Japanese mycologist Toji Nishida in 1911. It is characterized by having multinucleate hyphae, and by producing multiple spores on sporogenous cells.

The fungus was first isolated by Edgar Mathias Medlar in 1915 from a chronic skin lesion on the buttock of a 22-year- old man in Boston, Massachusetts who presented with verrucous lesions on the buttocks and feet. In consultation with Roland Thaxter, Medlar considered the fungus to represent a previously undescribed genus because the successive separation of the conidia and their maintained attachment to the cup-shaped portion of the sporogenous cells were unique characteristics not seen in any other genus. He named the genus Phialophora, meaning "shallow cup bearer" to represent the characteristic shape and the species epithet verrucosa, in reference to the resemblance of the lesion to "verrucous tuberculosis". Thaxter suggested that P. verrucosa should be classified under the subdivision, 'Chalarae' of Saccardo's classification system.
