The undulate plasmalemma or some invaginations of plasmalemma varied in size was observed in the meristematic cells.
The vacuolated cells had larger and more invaginating plasmalemma than those in the meristemate cells.
The plasmalemma was incorporated into planar bilayer lipid membrane and ion channels were measured by electrical methods.
And in the proximal area of the optic lobe, some neurons, which have a large nucleus and indented folded plasmalemma, are observed, and whose cytoplasm contains a small number of mitochondria.
