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.
For example, Dacrymycetaceae possess very large and irregularly shaped sterigmata as well as self-replicating spores, but have aseptate basidia. Tulasnellaceae have self-replicating spores and grossly swollen sterigmata that are separated from the basidium with a septum at the base, however the basidial body itself is not septate and the ...
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]
Invertebrates have several other types of specific junctions, for example septate junctions (a type of occluding junction) [4] or the C. elegans apical junction. In multicellular plants , the structural functions of cell junctions are instead provided for by cell walls .
An important category of septate uterus is the hybrid type a variant that may be misdiagnosed as bicornuate uterus when seen by laparoscopy [6] Professor El Saman From Egypt was the first to describe this anomaly and warned gynecologist about this common misdiagnosis, whenever there is a uterine fundus depression on laparoscopy gynecologists ...
Dark septate endophytes are plant root-colonizing fungi that are often darkly-pigmented, with septate hyphae, and form structures inside plant root cells such as microsclerotia. However, there is great variation in morphology within this group. Dark septate endophytes are observed more frequently in mature parts of the root system. [3]
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.
