In many different species, including our own, individual organisms organise themselves into communities to increase their overall fitness. This happens in unicellular organisms like Saccharomyces cerevisiae (Brewers Yeast), individual cells can arrange themselves into a variety of types of multicellular groups. These biotic groups are likely to provide an overall benefit to these yeast populations, an example is by protecting the organisms in the core of the structure from environmental stresses or by specialising functions to subpopulations within the community.
Yeasts can grow as isolated cells when suspended in shaking cultures, but they can also group into an extraordinary collection of types of groups, these can include flocs, flors, mats, colonies, and biofilms. These groups are found in natural habitats, in clinical settings like hospitals, and in factories—indeed, anywhere yeasts are found, outside of a laboratory, many yeast species are found in multispecies groups termed microbiomes, which can include other fungi or bacteria (Honigberg, 2011).
Japanese Blood Grass
When researching Japanese Blood Grass, it became difficult to find anything about the cellular organisation, I have therefore expanded my search to grass in general
The chemical structures of the primary cell walls of the grasses and their originators differ from those of all other flowering plant species. This is because they differ in the complex glycans that link and cross-link the cellulose microfibrils to create a strong framework, in the nature of the gel matrix surrounding this framework. Despite the wide differences in how the cell walls are composed, the developmental physiology of grasses is remarkably similar to that of all flowering plants. The grass cells respond similarly to environmental cues and growth regulators, they also show the same changes in physical properties of the wall to allow cell growth and possess similar patterns of wall biogenesis during the development of specific cell and tissue types. The possible unifying mechanisms of growth are suggested to explain how grasses perform the same wall functions as other plants but with different constituents and architecture. (Carpita, 1996)
when comparing Brewers Yeast and Japanese Blood Grass the cellular organisation of each one is different, brewers yeast is a rather simple organism whereas grass can be a relatively complex organism depending on the species of grass which is being looked at.
