Question

WHAT IS TRANSPIRATION?​

Answer 1

Answer:

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.

Transpiration is the process in which plants release the water inside it in the form of moisture or water vapor. Roots consume some amount of water from the soil and the rest evaporates in the atmosphere.

Types of Transpiration:-

Depending on the organ that performs transpiration, the different types are:

___________________________________

Stomatal transpiration: It is the evaporation of water through stomata. 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. Cuticular transpiration is lesser in xerophytes because they have thicker cuticles.

Lenticular Transpiration: It is the evaporation of water through lenticels. Lenticels are the tiny openings present on the woody bark.
