Eukaryotic cells display a wide variety of different cellmorphologies. Possible shapes include spheroid, ovoid, cuboidal, cylindrical, flat, lenticular, fusiform, discoidal, crescent, ring stellate, and polygonal (Figure 2). Some eukaryotic cells are irregular in shape, and some are capable of changi...
This results in the formation of a zygote that in turn undergoes meiosis (meiosis 1 and meiosis II) to produce 4 haploid cells. Asexual ReproductionAsexual reproduction, which is the most common mode of reproduction among trichonympha species, occurs through binary fission. This occurs through a ...
This diversity has originated from the spread of a sex-limited meiosis suppressor through species that originally reproduced by cyclic parthenogenesis. The confused state of cladoceran taxonomy is partially a consequence of the presence of such obligately asexual groups, but also results from the ...
Because the number of recombination events per meiosis is relatively small, tagging a causal variant requires only a few genetic markers per chromosome. The downside of the small number of recombination events is that the mapping resolution, i.e., how close to the causal variant one can get ...
But general characteristics that are frequently seen within the group include: Contains pseudopodia Are unicellular that do not form tissues Are amoebas Passively catches food that comes into their path using pseudopodia Are not photosynthetic Instead of the Rhizaria supergroup being defined by specific...
Green algae are also a paraphyletic group, a kind of taxonomic group that has a common ancestor but does not include all of the descendants of that common ancestor. Let me explain what that means a bit more using more familiar living creatures since it might be a confusing term and definiti...

Phylum Deuteromycota are called incomplete fungi because they reproduce only by releasing spores. The other groups of fungi reproduce both by spores and by cells joining together through meiosis. A well-known fungus from this phylum isPenicillium, used to make the antibiotic drug penicillin. ...
