2. Vacuole, Cytoplasm, Cell wall respectively.
3. Cytoplasm, Cell membrane and vacuole respectively.
4. Cytoplasm, Cell wall and Vacuole respectively.

(b) B in the figure represents :

1. Osmotic pressure
2. Turgor pressure
3. Wall pressure
4. Diffusion pressure

(c) A in the figure represents :

1. Imbibition pressure
2. Wall pressure
3. Turgor pressure
4. Osmotic pressure

(d) C in the figure represents :

1. Turgor pressure
2. Osmotic pressure
3. Wall pressure
4. Imbibition pressure

(e) Draw a neat and labelled diagram of a plasmolysed plant cell.
