Plant Structure and Function
Plant fibers such as cotton and linen are produced by the vascular tissue system of plants. The vascular tissue contains many long, slender cells that form long tubes and have walls that are reinforced by lignin.
Xylem is one of the two types of transport tissue in vascular plants, the other being phloem.The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients. The word "xylem" is derived from the Greek word ξύλον (xylon), meaning "wood"; the best-known xylem tissue is wood, though it is found throughout a plant.
Plant Stem: Function, Types & Parts
The xylem is a network of tubes that transport water and minerals throughout the plant. Think of the xylem as a straw that sucks water from the roots up to the rest of the plant. The xylem also ...

Components of a Hydropower Plant and their Functions
7. Draft Tube. If reaction turbines are used, then draft tube is a necessary component which connects turbine outlet to the tailrace. The draft tube contains gradually increasing diameter so that the water discharged into the tailrace with safe velocity. At the end of draft tube, outlet gates are provided which can be closed during repair works.
What is Draft Tube ? its function, types and advantages
The main function of the draft tube is to convert the Kinetic energy of water into pressure energy. The draft tube brings the pressure of the water exiting the turbine back to atmospheric pressure levels by reducing the velocity of the water at the tailrace. Cast steel and cemented concrete are the materials used to build the draft tube.
What Is the Function of a Stigma in Plants?
· The function of the stigma in a flower is as a pollen receptor. The stigma is a sticky tip on the top of a carpel. The stigma is contained inside of the pistil, which also contains the ovary, style and carpel. A pistil may have several carpels. The style is the part of the flower, also called a stalk, that allows pollen tubes to grow from grain.
Functions of xylem and phloem
Plants have transport systems to move food, water and minerals around. These systems use continuous tubes called xylem and phloem: - Phloem tubes carry sugar & other organic nutrients made by plant from the leaves to the rest of the plant.
