Measuring Rate of Rater Uptake by a Leafy Shoot :: Papers

Measuring Rate of Rater Uptake by a Leafy Shoot The water supply pulmonary tuberculosis can be heedful easily and because very high proportion of the water taken up by a stem is lost in transpiration, it enables the rate of transpiration to be measured. Key Factors to be kept Constant - ================================== v Temperature - room temperature (approximately 25C) v Wind speed - No artificial wind was produced to go results v Light intensity - Extra light was not apply v Humidity - it was not humid on the day experiments were conducted The water uptake for the control Experiment. Time (minutes) Initial meniscus position of the oxygenise gurgle (cm) Final meniscus positionof the air let the cat out of the bag (cm) Water uptake (Distance moved) (cm) wide water uptake (cm) 1 10.0 10.7 0.7 0.7 2 10.7 11.5 0.8 1.5 3 11.5 12.3 0.8 2.3 4 12.3 13.0 0.7 3.0 5 13.0 14.0 1.0 4.0 6 14.0 14. 8 0.8 4.8 The water uptake when Vaseline is applied on the superlative surface of the leaves.
