Question

Observe the relationship between the first two pairs and then fill in the suitable word:

(a) Plasmolysis: Exosmosis:: Deplasmolysis:____________.

Answer 1

Relationship between plasmolysis and exosmosis:

1. Plasmolysis is a process of cell shrinkage caused due to the loss of water. It occurs due to exosmosis.
2. Exosmosis is a process of outward movement of water molecules through the cell membrane from a region of low solute concentration of the cell to a high solute concentration region of the surrounding environment.
3. Plasmolysis is observed when a cell is placed in a hypertonic solution.

Relationship between deplasmolysis and endosmosis:

1. Deplasmolysis is a reverse process of plasmolysis. It occurs due to endosmosis.
2. Endosmosis is the inward movement of water molecules from a region of low solute concentration to a high solute concentration.
3. Deplasmolysis is the swelling up of plasmolyzed protoplast when the cell is placed in a hypotonic solution.

Final answer: Plasmolysis: Exosmosis:: Deplasmolysis: Endosmosis.
