Question

What fills the space between cell wall and membrane?

Answer 1

After plasmolysis the gap between the  cell wall  and the cell membrane  in a plant cell  is filled with hypertonic solution. ... Most animal cells  consist of only a phospholipid bilayer (plasma membrane) and not a cell wall, therefore shrinking up under such conditions.

Answer 2

Water is present between cell wall and plasma member in plasmolysed cell.
