Why does water in the potometer tubing move into the shoot?
Plant evaporate water from the leaf and cause capillary effect to pull the water through the shoot.
What happen to voltage sensitivity if current sensitivity is increase of agalvanometer?
it also increases
What is the difference between calibration sensitivity and analytical sensitivity?
Calibration Sensitivity(m): slope of acalibration curve at the consentration of interest y=mx+n m:slope(Calibration Sensitivity) x:concentration n:signal of blank Analytical Sensitivity: response to noise ratio A.S=m/S m:slope S:standard deviation of the measurement
What is the relation of Figure of merit with current sensitivity?
Figure of merit = 1/ Current Sensitivity.
What you mean by sensitivity of potentiometer?
Sensitivity of potentiometer: A potentiometer is said to be more sensitive, if it measures a small potential difference more accurately.
Why is it necessary to seal the joint between the stem and the potometer with the vaseline?
to prevent the air from the atmosphere flow into potometer
What instrument measures water uptake in plants?
Potometer
Which is the apparatus used to demonstrate osmosis is called?
potometer
Why do you think it is necessary to have an airtight seal in the potometer?
Having an airtight seal in the potometer is necessary to ensure that there is no air leakage into the system, which could disrupt the measurement of water uptake by the plant. An airtight seal helps maintain a constant pressure within the potometer, allowing for accurate and reliable measurements of transpiration rates.
What instrument measures moisture in soil?
TensiometersProtimeter products and instruments for measuring moisture and temperature in materials and the environment. Such instruments are used for wood, civil engineering and agriculture or any area where the presence of moisture is to be detected
Can anything be done to improve the sensitivity to the penis?
The sensitivity of the penis can be affected if a person has masturbated frequently over the course of time. This can be improved by limiting masturbation and using more lubricant when masturbating. It won't change overnight, but over time a person should experience more sensation.
Which characteristic is shown when a person smells a gas in the air?
Sensitivity
Why the rate of water movement in an intact shoot is less than that measured in the potometer?
there is resistance to water movement across root cortex.
Why is it necessary to cut the leafy shoot and fit it into the potometer under water?
To minimise the contact between the air and the cut end of the leafy shoot
Why does water in the potometer tubing move into the shoot?
Plant evaporate water from the leaf and cause capillary effect to pull the water through the shoot.
What is sociocultural sensitivity?
what is socio -cultural sensitivity
Why does the potometer not measure transpiration accurately?
Because not all of the water that is taken by the plant is used for transpiration. Some of the water taken might be used for photosynthesis or by the cells to maintain turgidity. The potometer measures the rate of uptake of water. To measure transpiration rate directly, rather than the rate of water uptake, utilize a scientific instrument which quantifies water transfer at the leaves.
