Given above is the diagram of an experimental setup to study the process of transpiration in plants. Study the same and then answer the questions that follow:
(a) Name the color of dry cobalt chloride paper?
(b) Is the experimental leaf a monocot or a dicot? Give a reason to support your answer.
(c) Why are glass slides placed over the dry cobalt chloride papers?
(d) After about half an hour what change, if any, would you expect to find in the cobalt chloride paper placed on the dorsal and ventral sides of the leaf? Give a reason to support your answer.
What is the characteristic feature of the cobalt chloride paper used in the transpiration experiment?
The diagram given below represents an experimental set-up to demonstrate a certain process. Study the same and answer the questions that follow:
(a) Name the process:
(b) Define the above-named process.
(c) What would you deserve in the experimental set-up after an hour or so?
(d) What control experiment can be set up for comparison?
(e) Keeping in mind the root-hair, cell and its surroundings, name the parts that correspond to
(1) concentrated sugar solution (2) parchment paper and (3) water in the beaker.
(f) Name any other substance that can be used instead of parchment paper in the above experiment.
(g) Mention two advantages of this process to the plants.
