A potometer with a leafy shoot weighed 18.9g initially and weighed 17.9g after one hour. From this it follow that
- the shoot absorbed 1g of water per hour
- 1g of water per hour evaporates from the potometer
-
the shoot lost 1g of water per hour
- the potometer water receded at the rate of 1g per hour
- the shoot was respiring and lost weight at rate of 1g per hour
The correct answer is: C
Explanation
The amount of water lost is (18.9 - 17.9)g = 1g. Hence, the water lost by the shoot is 1g.
