What is meant by the term transpiration stream?
Explain the Term
Transpiration
Differentiate between transpiration and guttation.
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.
Write the correct answer out of the five available choices given under each question:
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?
(i) A (ii) B (iii) C (iv) D (v) E
III. Which plant would remain healthy for a longer period of time?
(i) A (ii) B (iii) C (iv) D (v) E
IV. In this experiment which plant can be considered as the uncontrolled one?
(I) A (ii) B (iii) C (iv) D (v) E
V. The difference of weight would b maximum between:
(i) A and B (ii) A and C (iii) A and D (iv) A and E (v) D and E
