If you plasmolyse a cell the cell membrane will still enclose and be in
contacr with the cytoplasm; it does not really have mush altermative
other than to remain in contact with an aqueous phase, even a thin one.
Obviously as you plasmolyse the cell its volume will decrease and at some
point its surface area: this loss of surface area will require a loss of
surface membrane area. At least when plant tissues freeze the dehydration
of the cell contents (which do not initially freeze) forces membrane
resizing by invaginations and (Ithink) vesicle formation.
all the best,

Hi,
anyone knows what is in the gaps when a plant cell is plasmolysed? As
in, the cell's membrane and cytoplasm? Is it just air, or something
else?
