I think that you guys did a great job at introducing the topic. It was very relevant and broke the topic down into small pieces that allow the reader to understand what you are talking about on a basic level. I would recommend reviewing your second paragraph about structure. If the title of the paragraph is "structure" then I would only talk about that in this section. If you are going to dive into other aspects of the cannula then I would create separate paragraphs that divide the information more. Make sure that if you are stating a fact in that second paragraph that is cited given that you did not actually come up with the information.

Cannula
Cannula (or cannulae) is the term to describe hollow structures which resemble tubes that are only found in certain archaea cells. Specifically identifying family members of the Pyrodictium genus, many examples have been examined from hydrothermal marine locations which harbor temperatures of 80-110 degrees Celsius. When observed in close proximity, cannula appear hollow with a diameter of 25nm.Unfortunately the cannula are not well understood or studied.

Physical Structure
Cannula function as an intracellular connection of periplasmic spaces between differing cells. Although this is the physical function, the network function is still not clear. It has been hypothesized that this network connection might be used to exchange genetic material or nutrients, which could contribute to the cells ability to survive unfavorable conditions. At present time there is very little known about the inner working of the cannula tubule and what might happen there. When observed in close proximity, cannula appear hollow with a diameter of 25nm.They have been found to be resistant to high heat conditions and many forms of denaturing agents. This has been proven by observing no morphological changes when subjected to high temperatures and and sodium dodecyl sulfate.

The physical makeup of cannula are consistent with three different and homologous glycoprotein subunits that have different masses of 20, 22, and 24 kDa. This unique makeup and the identification of only belonging to archaeon-specific cells are a novel finding that could possibly contribute to finding out new information about the assembling structures of prokaryotes function.

It is found that the growth of these networks is directly related to cell division. When a cell of this type undergoes division, the daughter cells remain connected to their parental cell via these tubules, which exponentially grows the network structure with the division. This means that each cell has multiple cannula connections in a dense form. Specimens of this nature have been studied in laboratories where cultures have been maintained for up to 20 years, but in this 20 years they have never been able to produce a strain that does not grow the cannula. This suggests vital necessity
