does the process of transpiration plays an important role in bringing back the water to the surface if yes explain
Answers
Explanation:
Transpiration is the loss of water in the form of water vapour from the aerial parts of a plant.
It occurs through openings called stomata.
Water loss through evaporation lowers the concentration of water inside the mesophyll cells.
Due to this, water enters mesophyll cells from neighbouring xylem vessels through osmosis.
As water evaporates from the leaves, a suction force is created. This force helps to draw more water up through the stem which causes the roots to absorb more water from the soil.
Higher the rate of transpiration, greater the rate of absorption of water and solutes from the soil.
Transpiration also helps in maintaining the temperature of the plant body.
Answer:
he contacts are not connected as well as they appear.
The wires have been tied or clamped to the terminals without stripping off the insulation.
Optical fibre was used instead of metallic wire.
The bulb is dead (burnt out).
The battery is dead.
There is no voltage source in the circuit.
A switch in series is open (switched off).
Something in series is blocking most or all of the current because, for example,
it's defective/burnt out or
it's a capacitor and the voltage supply is DC.
Something in parallel is passing too much of the current, bypassing the bulb. For example:
an extra wire,
an inductor and the voltage is DC, or
the circuit is immersed in water or mercury.
The voltage is too low to light the bulb.
The bulb is really an LED and is wired backwards.
The bulb is a tulip bulb instead of a light bulb.
The bulb is glowing but your eyes are closed.
