Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector $\vec{P}$ of magnitude, 4 × 10^-6 C m, is ± 9 × 10³ V.
(Take $\frac{1}{4\pi\epsilon_0}=9\times10^9$ SI units)
Reason R : $V=±\frac{2P}{4\pi \epsilon_0r^2}$, where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Transpiration

The process by which the plant body releases water in the form of vapors through its aerial portions is known as transpiration. The evaporation of water from the plant portion is also known as transpiration. It is a crucial function in plants that aids other processes and maintains water and nutrient balance. It provides a number of benefits for the plant's body.

Types of Transpiration:

There are three different types of transpiration in plants:

Stomatal Transpiration: It is the evaporation of water from a plant's stomata. The majority of the water from the plants is lost through transpiration. When the stomata open, the water at the surface of the leaves turns into vapor and evaporates.
Lenticular Transpiration: Lenticels are tiny openings in the bark of branches and twigs that allow light to pass through. Lenticular transpiration is the process of water evaporating from a plant's lenticels. Lenticels aren't found in every plant. Through lenticels, only a small amount of water is lost.
Cuticular Transpiration: It is the evaporation of water from a plant's cuticle. The cuticle is a waxy layer that covers the surface of the plant's leaves. Cuticular transpiration loses about 5-10 percent of the water from the leaves. More water is transpired via the cuticles during dry conditions when the stomata are closed.
