Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is the predominant type of transpiration?
A
cuticular transpiration
B
lenticular transpiration
C
perspiratory transpiration
D
stomatal transpiration
Explanation: 

Detailed explanation-1: -Stomatal transpiration-This is the most dominant form of transpiration.

Detailed explanation-2: -More stomata will provide more pores for transpiration. A leaf with a bigger surface area will transpire faster than a leaf with a smaller surface area. A waxy cuticle is relatively impermeable to water and water vapor and reduces evaporation from the plant surface except via the stomata.

Detailed explanation-3: -Stomata are specialized pores in the leaves. They account for around 80 to 90% of the total water loss from the plants. Cuticular transpiration: Cuticle is an impermeable covering present on the leaves and stem. It causes around 20% of transpiration in plants.

Detailed explanation-4: -Stomatal transpiration accounts for almost 90% of the total transpiration. Cuticular transpiration accounts for 5-10 % whereas, lenticular transpiration accounts for 0.1% of the total transpiration.
