Aseptate (non-septate) or coenocytic (without septa) Non-septate hyphae are associated with Mucor , [ 9 ] some zygomycetes , and other fungi. Pseudohyphae are distinguished from true hyphae by their method of growth, relative frailty and lack of cytoplasmic connection between the cells.
Septate junctions are in a tight arrangement which is parallel to each other. [4] For the septate junctions, several components are related to the function or the morphology of septate junctions, like Band 4.1-Coracle, Discs-large, fasciclin III, Neurexin IV (NRX) and so on. [5] [6] Band 4.1-Coracle is necessary for the interaction of the cell. [6]
A coral septum is one of the radial calcareous plates in the corallites of a coral. [18]Annelids have septa that divide their coelom into segmented chambers. [19]Many shelled organisms have septa subdividing their shell chamber, including rhizopods, cephalopods and gastropods, the latter seemingly serving as a defence against shell-boring predators.
The intestinal eugregarines are separated into septate – suborder Septatorina – and aseptate – suborder Aseptatorina – depending on whether the trophozoite is superficially divided by a transverse septum. The aseptate species are mostly marine gregarines. Urosporidians are aseptate eugregarines that infect the coelomic spaces of marine ...
In the aseptate (or acephalate) species the cell is not divided. In the septate (or cephalate) species the body is divided into at least 2 parts: a posterior portion which contains the nucleus (the deutomerite) and an anterior portion (the protomerite), which forms the epimerite. In some species the deutomerite may be further subdivided.
The septal area (medial olfactory area), consisting of the lateral septum and medial septum, is an area in the lower, posterior part of the medial surface of the frontal lobe, and refers to the nearby septum pellucidum.
In addition to having septate basidia, heterobasidiomycetes also frequently possess large irregularly shaped sterigmata and spores that are capable of self-replication – a process where a spore, instead of germinating into a vegetative hypha, gives rise to a sterigma and a new spore, which is then discharged as if from a normal basidium.
Phycomycetes is an obsolete [1] [2] [3] polyphyletic taxon for certain fungi with aseptate hyphae. [4] It is used in the Engler system. [5] Asexual reproduction takes place by zoospores (motile) or by Aplanospores (non-motile). These spores are endogenously produced in sporangium. A zygospore is formed by fusion of two gametes.
