Hello Dear.
Here is the answer---
→→→→→→→→→→
A. We know, the water is the Hypo-tonic solution and sugar solution is the Hyper-tonic Solution.
When a Piece of Potato is put into the sugar solution, the Potato get Plasmolysed, because the Water molecules from the Potato moves into the sugar solution.
When a Piece of Potato is put into the Water solution, The potato get swells, because the water molecules moves from the Solution into the potato.
↔↔↔↔↔↔↔↔↔
B. In First Case(Sugar Solution),
We know, Sugar Solution is the Hypertonic Solution. When Potato is Put into the sugar solution, Exoosmosis(Outward movement of the solvent molecules by the process of Osmosis is called as Exoosomosis.) takes place thus Potato Get Plasmolysed.
In Second Case(Water Solution)
We know, Water is the Hypotonic Solution.When potato is put into the Water Solution, Endoosmosis[Inward Movement of the Solvent Molecules by the Process of Osmosis is called as Endoosmosis] takes place. Due to Endoosmosis, water molecules moves into the Potato thus it gets swell.
↔↔↔↔↔↔↔↔↔
C. Since In this Transport there is no use of the Energy. Thus, the transport taking Place s the Passive Transport.
D. The Transport of the molecules in the given conditions is the Passive Transport.
Reason → There is no use of the Energy in any form for the Movement of the molecules in both the cases, thus this is an Example of the Passive Transport.
↔↔↔↔↔↔↔↔↔
E. Active transport is the movement of the substance from an area of Lower concentration to an area of Higher concentration across a Semi permeable Membrane. It requires Energy to take place.
