In this investigation, the amount of water taken up by a plant and the amount of water lost from the same plant were recorded. The readings were collected across an 18-hour period. The outcomes are displayed in Fig. 10.1.
(a(i))[1]
State the water uptake rate at 12:00 (midday).
(a(ii))[1]
State the time at which water uptake was 10 g per hour.
(a(iii))[1]
State one time in the day when water uptake and water loss were equal.
(b)[2]
Describe the effect of changes in temperature and changes in humidity on the rate of water loss in a plant.
(c)[1]
State the name of the process responsible for water loss from plants.
