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.
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]
Rhizopus is a genus of common saprophytic fungi on plants and specialized parasites on animals. They are found in a wide variety of organic substances, including "mature fruits and vegetables", [2] jellies, syrups, leather, bread, peanuts, and tobacco.
The Glomeromycota have generally coenocytic (occasionally sparsely septate) mycelia and reproduce asexually through blastic development of the hyphal tip to produce spores [2] (Glomerospores,blastospore) with diameters of 80–500 μm. [9] In some, complex spores form within a terminal saccule. [2]
Cutaway of a nautilus shell showing the chambers. Septa (singular septum) are thin walls or partitions between the internal chambers of the shell of a cephalopod, namely nautiloids or ammonoids.
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.
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 ...
