Question

What occupies the space between the cell wall and the shrunken protoplast in the plasmolysed cell? 2 what would be the psi pressure of a flacccid cell? Which organisms other than plants possess cell wall?

Answer 1

1st.

The outer solution with high salt concentration (hypertonic solution) occupies the space between the cell wall and the shrunken protoplast in the plasmolysed cell. ... A plasmolyzed cell, where the plasma membrane has pulled away from the cell wall, has a negative pressure potential.

2.

The value of pressure potential is equal to the value of turgor pressure. Pressure potential is negative in a plasmolysed cell and xylem vessel, positive for a turgid cell and zero for a flaccid cell.

3.

Bacteria and some fungi
