Given below is an apparatus used to study a particular process
in plants. Study the same and answer the questions that follo
(i)Name the apparatus.
(ii)Mention one limitation of this apparatus.
(iii) Which phenomenon is studied with the help of this apparati
(iv)What is the function of the part marked reservoir?
(v)What is the role of the air bubble in the experiment?
Answers
Answer:
a) Ganong's potometer
b)The Potometer does not measure the rate of transpiration accurately because not all of the water that is taken by the plant is used for transpiration
c) transpiration
d)The function of the reservoir is to allow the air bubble to travel back to the start of the measuring scale on repeating the experiment
e) the moving distance of air bubble divided by the time gives the rate of transpiration
please mark as BRAINLIEST
Answer:
(i) Potometer
(ii) The introduction of an air bubble in the horizontal bar is very difficult and time-consuming.
(iii) Transpiration
(iv) Reservoir helps the air bubble to travel back to the start of the measuring scale when the experiment is repeated.
(v) The air bubble in the potometer moves with the uptake of water by the plant and the distance travelled by the bubble in a given time gives the rate of the transpiration.
