Transpiration pull will be maximum under which set of the following conditions?
Suppose you have a small rose plant growing in a pot. How would you demonstrate transpiration in it?
Choose the correct answer:
In herbaceous plants, following percentage of absorbed water comes out __________
Given below is an example of a certain structure and its special functional activity:
chloroplasts and photosynthesis
In a similar way, write the functional activity against the following:
Xylem and ______
What are lenticels? Where are they found?
The figure given below represents an experimental setup with a weighing machine to demonstrate a particular process in plants. The experimental set-up was placed in bright sunlight. Study the diagram and answer the following questions:
- Name the process intended for the study.
- Define the above mentioned process.
- When the weight of the test tubes (A and B) is taken before and after the experiment, what is observed? Give reasons to justify your observations in A & B.
- What is the purpose of keeping the test tube B in the experimental set-up?
- What is the purpose of putting oil in the test tube?
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
Give Technical Term
The apparatus used to compare the rate of transpiration in cut shoot.
Write the functional activity of the following structure:
Hydathodes
