Answer to prex:
Comments to points 1 to 3:
1. You are probably right, that the stiffness of the wall is comparably small to the pressure factor. Still ..... the fact that I can notably influence the stiffness of the apical part tells me the the wall plays a role. Actually, the biology is even...
Thanks Prex and the others for your ideas.
I need to add two things:
1. The cell wall is probably not just a membrane, since it does not collapse upon removal of turgor. It stays cylindrical, even though the resistance to deformation decreases by a factor 20. So I probably have to calculate...
First of all, I am biologist and know NOTHING about mechanical engineering or finite element analysis - so please forgive my amateur approach.
I would like to model the stiffness of a single plant cell, a pollen tube. It could be described as a fire hose kind of pipe (length up to several...
PS: Forgot to mention, ideas and calculations that contribute substantially to the eventual model of my pollen tube might be rewarded with a co-authorship on a scientific paper. Promised!
Hi JAE and Prex,
thanks for getting back to me so quickly. I will provide more details on the subject, as required. Remember, I am a TOTAL amateur regarding physics and engineering, so I probably use the wrong vocabulary, but I hope you will be able to convert this into proper engineering talk...
