What is Lenticular Transpiration- Lenticular transpiration is found only in the woody branches and some fruits where lenticels occur.

Factors Affecting the Rate of Transpiration in Plants depends on 2 main reasons –
Plants Parameters
Environmental Conditions
Transpiration is the process of loss of water in the form of water vapor from the leaves and other aerial parts of the plant.
Significance of Transpiration
Cooling
Absorption of water
Creating Suction force
Transportation of water
Transportation of Minerals
Protection from heat injury
Plants transport water and minerals through specialised structures called xylem and phloem. Xylem moves water and nutrients from the roots to the rest of the plant, while phloem transports sugars and other organic compounds produced during photosynthesis to the rest of the plant. This process is essential for plant growth and survival and is facilitated by a combination of physical and chemical mechanisms.

Stomatal transpiration is a critical process by which plants regulate their internal water balance and maintain proper hydration. The process involves the movement of water vapour through the stomata in a plant’s leaves, which is regulated by a variety of environmental factors. Stomatal transpiration is also important for regulating plant temperature and promoting growth and development. Environmental factors such as drought, excess water and pollutants can impact stomatal transpiration.

Excretion removes the unwanted or waste by-products of metabolic pathways which unnecessarily hinder the chemical equilibrium of reactions.Excretion and osmoregulation regulate the ionic concentration of body fluids.
5 Important Significance of Excretion and Osmoregulation Read MoreThe process of regulating water content and ion concentration in the body of an organism is called Osmoregulation.
Osmoregulation is related to the habitat of an organism. In human beings this function is performed by the kidneys.
The process of removal of toxic wastes from the body of an organism is called Excretion.
The major Excretory products of Animals are Nitrogenous compounds such as Ammonia, Urea and Uric acid, Bile pigments, Water and Small Amounts of other waste products.
Dialysis is an artificial process used to remove water and waste substances from the blood when the kidneys fail to function properly.
Dialysis works on the principles of the diffusion of solutes and ultrafiltration of fluid across a semipermeable membrane.
Why Is Dialysis (Haemodialysis) Necessary?
The total amount of Urine Produced is regulated by:
The total amount of Nitrogenous waste Produced.
