During their research, the authors also discovered that the spread of alcobioses is aided by small gastropods who often feed on corticioid fungi. Their excrements contain viable cells of algae and fungi who give rise to new alcobiotic coating shortly after. This type of reproduction is similar...
"Sexual reproduction does not require males and females, all it requires is the fusion of sex cells from two different mating types." The classic theory to explain the evolution of different size sex cells and therefore different sexes is the Disruptive Selection Theory and was proposed in the ...

Sexual reproduction may be isogamous, anisogamous or oogamous. Union of gametes may take place in water or within the oogonium (oogarnous species). The gametes are pyriform (pear-shaped) and bear two laterally attached flagella. The common forms are Ectocarpus, Dictyota, Laminaria, Sargassum ...

These cells of blue-green algae, also known as cyanobacteria, a kind of single-cell microorganism, have been modified using synthetic biotechnologies like gene editing. Featuring high reproduction speed and excellent efficiency of photosynthesis, they "eat" air and can produce organic compounds like ...
3). We used the tree to name some of the unknown species based on their chlorotype. If a chlorotype was shared between a unique known CCA species and unknown CCA, all unknown CCA bearing this chlorotype were assigned to this known species (e.g. all unknown CCA having chlorotype asv...
Sexual reproduction was not observed. The SEM images explained the approximately smooth cell wall surface. This species differs from C. tenuitheca by the ellipsoidal and ovoid cell shape in young age, and differs from C. vacuolata by the independent phylogenetic position based on 18S+ITS and ...
The diagnostic packet-formation during sexual reproduction in the Bangiales, and as reasonably posited for Bangiomorpha, has subsequently been reported in three species of the Compsopogonophyceae indicating that this feature has evolved at least twice within the red algae. It is thus possible ...
