5.3-9. Water lily leaf. This section has caught the body
of the astrosclereid, two of its arms, and just the base of three
more arms. If we could examine the back and front side of the cell (the parts
that have been cut away) we would undoubtedly see many more arms. Arms may
extend out freely into the intercellular spaces or lie embedded in a mass of
parenchyma. This is a very lucky section -- it has caught the cell's nucleus,
located in an arm rather than in the body.
