message: Cellulose recycling is one of the important bio-geo-cycling events that maintain the integrity of our ecosystem. There is no good write up on this. Also there is no material on its biochemistry. I have added a few material in the chemistry section, but require help in cleanup and material addition

text: By the way, the second sentence in the article is "It is a structural polysaccharide derived from beta-glucose.

message: Can someone help here?  I believe this article incorrectly identifies Cellulose several time as a hydrophilic compound.  I've worked with cellulose and most scientist know that it not soluble in water.  Wiki suggest that the term hydrophile means that compound should be soluble in water whereas cellulose is clearly not.  Shouldn't this compound be listed as hydrophobic?  —Preceding unsigned comment added by ChromExpWiki (talk • contribs) 16:08, 20 September 2010 (UTC)

thread_title:  Incorrect Link 

message: The diagram of cellulose in the cell wall is incorrect, misleadingly naïve and frankly just totally wrong. To (flagrantly) misquote Eric Morecambe, it has some of the right bits, but not necessarily in the right order, or orientation.  The sizes of the primary and secondary cell walls relative to the cell are unrealistic. The cellulose microfibrils in the wall are never orientated radially as shown but always parallel to the wall surface.  In the secondary wall they commonly form helicoids. The inner surface of the secondary wall (if that is what this unlabeled yellow/green layer is supposed to be??) does not have perforations in it (Alternatively, could it be a nightmarish representation of a nuclear membrane?) and what are the cellulose molecules supposed to be doing docking with the pores.  Please can we get rid of this diagram? It inaccurate, unscientific and brings the article only discredit.  Plantsurfer (talk) 14:40, 4 April 2013 (UTC)
