The filament is a thin tubular part of the stamen, which extends and supports the pollen sac at the top. The function of filaments in plants is to carry nutrients to the anther, where the pollen develops.
What are the functions of filament in flower?
The filament holds the anther up. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary. Male reproductive cells travel down the tube and join with the ovule, fertilizing it.
What is the function of the filament in a light bulb?
A filament lamp is a common type of light bulb. It contains a thin coil of wire called the filament. This heats up when an electric current passes through it, and produces light as a result. The resistance of a lamp increases as the temperature of its filament increases.
What is the function of the filament on the stamen?
Stamens are the male reproductive organs of flowering plants. They consist of an anther, the site of pollen development, and in most species a stalk-like filament, which transmits water and nutrients to the anther and positions it to aid pollen dispersal.
What is filament short answer?
Answer: The filament is the part of the light bulb that produces light. Filaments in incandescent light bulbs are made of tungsten. When electric current goes through the filament, the filament glows.
What is a filament in physics?
Definition: The metal resistance wire inside a bulb which transfers electrical energy to light (and heat).
What is filament in Class 6?
An electric bulb is a device which produces light when electricity is passed through its terminals. The bulb has two thick contact wires in the center with a thin wire attached between them. This thin wire is called filament.
What is the function of a filament in an electric bulb Class 6?
Answer: Function of an electric bulb is to produce light energy from the electricity passing through its filament. The filament gets heated up as the electricity passes through it.
What is a filament in biology?
: a single thread or a thin flexible threadlike object, process, or appendage especially : an elongated thin series of cells attached one to another or a very long thin cylindrical single cell (as of some algae, fungi, or bacteria)
What is electric filament?
filament in Electrical Engineering
A filament is the thin wire inside a light bulb that emits light when heated by an electric current. The incandescent light bulb makes light by heating a metal filament wire to a high temperature until it glows.
How does the filament help ensure pollination?
Filament function is to hold the anthers up within the flower, making the pollen more accessible to pollinators and the wind. Flowers come in all sizes, designs and shapes, but generally, filaments extend the anthers up from the base of flowers. The female reproductive part of the flower is called the pistil.
What is filament in one sentence?
a thin wire (usually tungsten) that is heated white hot by the passage of an electric current. (1) The working part of a filament lamp is a metal coil which glows white hot. (2) Yank on one filament in the web, and the other filaments had to move, too.
What is filament Class 6 short answer?
Filament is usually made of very thin tungsten wire. It is the filament of the bulb which glows when electricity from cell is passed through it. (3) The two thick wires inside the glass bulb provides support to the filament and also make the connection of the filament to the outer circuit.
What is a filament in astronomy?
Cosmic filaments are strands of dark matter and galaxies that rotate (illustrated). As the filaments spin, they pull matter into their orbit and toward galaxy clusters at each end.
Is filament a conductor?
A filament in a light bulb does have a resistance, however, it is a conductive metal meaning that it has a naturally low resistance anyway. When you put a relatively high voltage across a negligible resistance, you get maximum current.
What is a filament Wikipedia?
Protein filament, a long chain of protein subunits, such as those found in hair or muscle. Part of a stamen, the male part of a flower. Hypha, a thread-like cell in fungi and Actinobacteria. Filamentation, an elongation of individual bacterial cells.
What is a filament Class 7?
filament is a conducting wire with a high melting point, forming part of an electric bulb or thermionic valve and heated by an electric current. the filament of bulbs is made up of tungsten.
What is a filament Ncert?
The part of an electric bulb that glows is called the filament.
What is filament made up of?
Filaments in incandescent light bulbs are made of tungsten. Whenever an electric current goes through the filament, the filament glows. It may also be known as the electron emitting element in a vacuum tube.
Which filament is used in bulb?
Incandescent light bulbs consist of an air-tight glass enclosure (the envelope, or bulb) with a filament of tungsten wire inside the bulb, through which an electric current is passed.
What is the function of a cell physics?
An electrical cell is an “electrical power supply”. It converts stored chemical energy into electrical potential energy, allowing positive charges to flow from the positive terminal to the negative one through an external circuit. This is called a current.
Which of the following has a filament?
Detailed Solution. The correct answer is Tungsten. Tungsten: A thin wire inside the bulb is known as filament.
How does a filament produce light?
Why does the filament glow? Electricity flowing through the filament is essentially just electrons moving along the wire. … The energy pushes the electrons further away from the nuclei of the atoms. As the electrons fall back, they emit photons of light.
Why is the filament of a flower yellow?
Anther. The top of the filament is the home to the anther, a larger and usually slightly elongated knob that is often coated with yellow, dusty pollen. Inside each anther are four sacs in which pollen is produced.
Where is the filament in a flower?
Filament. The thin stalk that supports the anther in the male portion of the flower.
What is example of filament?
A fine or slender thread, wire, or fiber. The part of a stamen that supports the anther of a flower, the stalk of a stamen. The definition of a filament is a slender fiber or thread. The slim part of the stamen that supports the anther is an example of a filament.
What is filament structure?
The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments. These structures give the cell its shape and help organize the cell’s parts. In addition, they provide a basis for movement and cell division.
What are the properties of the filament Class 6?
- High melting point.
- Low vapor pressure.
- Free from oxidation in inert gas (i.e. argon, nitrogen etc.) medium at operating temperature (Non-corrosive).
- High resistivity.
- Low thermal coefficient of expansion (High temperature resistance)
What is the function of an electrical switch in a circuit?
In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another.
What is conductor and insulator Class 6?
Summary. Materials that allow electric current to pass through them are called conductors. Materials that do not allow electric current to pass through them are called insulators.
What are filaments and voids?
Cosmic voids are vast spaces between filaments (the largest-scale structures in the universe), which contain very few or no galaxies. … Regions of higher density collapsed more rapidly under gravity, eventually resulting in the large-scale, foam-like structure or “cosmic web” of voids and galaxy filaments seen today.
What are filaments in cells?
In biology, a protein filament is a long chain of protein monomers, such as those found in hair, muscle, or in flagella. Protein filaments form together to make the cytoskeleton of the cell. They are often bundled together to provide support, strength, and rigidity to the cell.
