Gurchranji: Micromorphology is fine... or Microtopography may be apt... just because the new SEM machines can look even closer, like at 300,000 magnification, still does not make it look at thin sections and the inside cytoplasm etc... Whatever is on the surface, including surface of whatever is inside cells or sacks etc that can be fractured open is looked at...
But there is one caveat... if one purifies actin etc of cytoskeletal structures of a cell and then plates them, dries them, coats etc processes them, one can look at its structure, but that still is the surface morphology... of protein or whatever... Japanese market now has an open chamber SEM where wet tissues without processing or drying can be examined... I personally have not seen it, only a small brochure... so cant comment on it... ==== usha di =========== On Wed, Jan 11, 2012 at 9:54 AM, Gurcharan Singh <[email protected]> wrote: > Thanks Vijayasankar ji and Pankaj ji for these papers. > I have just given final approval to 3rd Indian edition "Plant Systematics, > Theory and Practice" due in January 2012 in which I have managed to > incorporate three major changes of 18th IBC (changing name from ICBN to > ICN, allowing English description or diagnosis for Valid publication and > allowing online publication for Effective publication; in addition to > single name for each Fungus (no separate form genera) and fossils), as also > incorporating Takhtajan (2009) and APG III classifications (which I could > not do in 3rd International Edition "Plant Systematics, An Integrated > Approach, which had gone out from me in September 2009, and published in > January 2010).
