Question
Differentiate between :
Turgidity and Flaccidity

Answer

 
TurgidityFlaccidity
 When the cell is filled with water, so that its cell wall   is   in a state of tension, it is said to be turgid and the   condition is called turgidity. When a cell loses water from its cytoplasm   under plasmolytic conditions, it is said to be   flaccid and the condition is known as flaccidity.
It is caused by endosmosis. It is caused by exosmosis.
 Plasma membrane is pushed against the cell wall. Plasma membrane is not pushed tightly against   the cell wall.

The apparatus shown here is Girreau’s poto-meter designed to demonstrate unequal transpiration from the two surfaces of a dorsiventral leaf. Before keeping the leaf in between the cups, anhydrous calcium chloride ($CaCl_2$) contained in two small vials were weighed and placed in both the cups. The ends of the cups were closed with corks through which two mercury manometers were connected. After a few hours, $CaCl_2$​​​​​​​ vials were taken out and weighed again.

(i) What is the purpose of keeping $CaCl_2$ vials inside the cup?
(ii) After a few hours, the $CaCl_2$ vials were taken out and weighed again. Will you expect any difference in weight? If so, give reasons.
(iii) What was the purpose of using a mano-meter?
(iv) What do you mean by transpiration?
