The following dia

Answer :

(a) The state of the cell shown in the diagram is known as the plasmolyzed state as the content of the cell is shrunken to its center.

(b) The structure that acts as the selectively permeable membrane is the cell membrane as it allows the passage of solution and specific ions but blocks the passage of solute molecules and other ions.

(c) If the cell would have been placed in distilled water, strong sugar solution would not have been observed in the space between the cell wall and the cell membrane and plasmolysis would not have occurred. In distilled water, which is a hypotonic solution, the cell thus observed would have been turgid.

(d) The one feature of this plant cell which is not present in an animal cell is the cell wall.

The outer covering of the plant cell which acts as a protective layer and provides the cell with mechanical strength and a definite shape is known as the cell wall. Animal cells are devoid of the cell wall, the final outermost covering in case of an animal cell is the cell membrane.
