| 1. | Water is given out in the form of water vapour. | Water is given out in the form of liquid. |
| 2. | Transpirated water is pure. | Guttated water is a solution because it contains dissolved salts and water. |
| 3. | Transpiration occurs through stomata, cuticle and lenticels | Guttation occurs through hydathodes. |
| 4. | Transpiration usually occurs during the daytime. | Guttation occurs during nighttime. |

The following diagram is set up to demonstrate an experiment.
Five plants A, B, C, D, and E were placed in a beaker containing water. The water in each beaker was covered with a layer of oil. The leaves were removed from plant D in plant B, upper surfaces of all the leaves were covered with Vaseline, in-plant C the lower surfaces of all the leaves were covered with Vaseline and plant E was exposed to strong light. The beakers were then left for a few hours and at the end of the experimental period, weights of each beaker were taken.

I. In which beaker would you expect the greatest decrease in weight?
(i) A (ii) B (iii) C (iv) D (v) E
II. In which beaker the change of weight would be minimum?
