Question

4. A student setup an experiment using a well-watered plant. The plant's roots and soil were covered
with a rubber sheet. The plant was then kept in a glass bell jar and sealed with Vaseline at the bottom
part to prevent the flow of air. The student keeps the apparatus in the light and observes water drops
inside the jar after 2 hours.
What can be evaluated about transpiration from this experiment?
(a) Plant leaves give off water in form of vapours.
(b) Heat from the outside warms the jar which melts the vaseline into vapours.
(c) Plant absorbs water from environment thus extra water appears on the inside of jar.
(d) Covered roots and stem of the plant decreases the temperature of jar resulting in condensation of
moisture into vapours​
