Comparison between Stomatal Transpiration and Cuticilar Transpiration
Stomatal Transpiration: Water vapour diffuses out through minute stomata present in soft above ground part of plant is known as Stomatal Transpiration. Of the total water loosed, near about 85 – 90% of water loosed by the stomatal transpiration.
- In organ of plants in which water transpiration occur: It occurs through stomata
- Quantity: About 85% transpiration occurs in this method
- Time: Stomatal Transpiration occurs only in light reaction
- Controlling: Stomatal Transpiration is controlled by guard cells
Cuticilar Transpiration: This type of transpiration depends upon the thickness of the cuticle and presence or absence of wax coating on the surface of the leaves.
- In organ of plants in which water transpiration occur: It occurs through cuticle
- Quantity: Only 10-15% transpiration occurs in this method
- Time: Cuticular transpiration occurs day and night
- Controlling: Cuticular transpiration is controlled by thickness and broken parts of cuticles.
