intercellular communication -- plasmodesmata
When leaf material is carefully
prepared, then is it possible to see the insides of cells, as is
the case in the micrograph to the left. Here, we can see what
the internal structure of this grass leaf looks like and can see
organelles (presumably chloroplasts) within the
cells. This is a longitudinal section of the leaf, and Kranz
mesophyll tissue occupies the central region.
depressions in this cell wall, are pitfields, containing large
numbers of plasmodesmata The unlabelled arrows point to a few
examples of these, in the the cell wall interface between the
Kranz mesophyll and bundle sheath cells in a C4
grass. The images was made using a Scanning Electron Microscope.
