A plant cell placed in hypotonic solution gets Plasmolysed.
The following diagram represents a plant cell after being placed in a strong sugar solution.
Guidelines 1 to 5 indicate the following
(1)Cell wall, (2) Strong sugar solution, (3) Protoplasm (4) Large vacuole, (5) Nucleus
(1)What is the state of the cell shown in the cell shown in the diagram?
(2)Name the structure which acts as a selectively permeable membrane.
(3)If the cell had been placed in distilled water instead of strong sugar solution, which feature would not have been seen?

Choose the correct answer:
Plasmolysis will occur when the cell is placed in a __________
In an experiment, two sets of apparatus were set up as shown below:
In A there is a concentrated sugar solution inside the thistle funnel and red ink in the water outside the funnel. In B there is a concentrated glucose solution with red ink inside the thistle funnel and water outside the thistle funnel.
In both A and B the level of liquid inside the funnels rises up the tubes. In A the sugar solution turns red and in B, the water turns red.
Study the given observations and answer these questions:
- Name the process by which red ink moves in A and B.
- Which type of pressure forces the water molecules to move towards thistle funnels and cause a rise in the water level?
- Where does this process occur in plants and animals?
- What material could be used as a semi-permeable membrane?
Name the following:
The movement of a liquid through a selectively permeable membrane.
Name the following:
Condition of cell in which the cell content are shrunken.
Explain the Term: Osmosis
Define the following term:
Osmotic Pressure
