Sample questions

1. 1.Match the items of Column A with those in Column B and select the correct option:

   	Column I		Column II
   (A)	Cactus	(i)	Exudation of sap from injured part
   (B)	Banana leaf	(ii)	Special pores at the tip of veins
   (C)	Hydathodes	(iii)	Water droplets along the margin of the leaf only in the morning.
   (D)	Bleeding	(iv)	Leaf spines

   Options: (a) (A) - (iv), (B) - (iii), (C) - (ii), (D) - (i) (b) (A) - (iv), (B) - (ii), (C) - (iii), (D) - (i) (c) (A) - (iv), (B) - (iii), (C) - (i), (D) - (ii) (d) (A) - (iv), (B) - (i), (C) - (iii), (D) - (ii)
2. 2.Why is the rate of transpiration higher on a windy day compared to a calm day?
   • A.Wind increases the temperature around the leaves, speeding up transpiration.
   • B.Wind removes water vapor from around the leaves, increasing the diffusion gradient.
   • C.Wind forces more water out of the stomata by physical pressure.
   • D.Wind enhances the absorption of water by the roots, increasing transpiration.
3. 3.Leaf spines
   • A.Prevents loss of water from the leaves due to evaporation.
   • B.Reduce the surface area so that the loss of water due to transpiration is reduced.
   • C.Causes the leaf to roll and prevent evaporation of water.
   • D.Allow for exchange of respiratory gases and prevent from browsing animals.
4. 4.Stomata:
   • A.Stomata help in diffusion of gases in the leaves and in transpiration.
   • B.Reduce the amount of water lost during transpiration
   • C.Regulate the opening and closing of guard cells
   • D.Reduce the intensity of incident light.
5. 5.The rate of transpiration is more when:
   • A.Atmosphere is dry
   • B.Temperature is high
   • C.Atmosphere is dry and temperature is high
   • D.Humidity is high
