(i) What is the state of the cell shown in the diagram?
(ii) Name the structure that acts as a selectively permeable membrane.
(iii) Label the parts numbered 1 to 4 in the diagram.
(iv) How can the above cell be brought back to its original condition? Mention the scientific term for the recovery of the cell.
(v) State any two features of the above plant cell which is not present in animal cells.

(i) The cell is in plasmolysed or flaccid state.
(ii) Plasma membrane
(iii) Parts numbered 1 to 4 are:
- 1 → Cell wall
- 2 → Strong sugar solution
- 3 → Cell membrane
- 4 → Nucleus
(iv) If the cell is placed in the hypotonic solution (water), the cell will be brought to it's original condition. The scientific term for the recovery of the cell is deplasmolysis.
(v) Cell wall, large prominent vacuole.
