Question

The correct match is
(i) An instrument used to measure transpiration pull.
(ii) An instrument used to measure the size of stomata.
(iii) An instrument used to measure the pressure of the fluid.
(iv) Amount of osmosis per unit time.

A (i) - Potometer, (ii) - Manometer, (iii) - Porometer, (iv) - Osmometer
B (i) - Porometer, (ii) - Manometer, (iii) - Potometer, (iv) - Osmometer
C (i) - Monometer, (ii) - Potometer, (iii) - Porometer, (iv) - Osmometer
D (i) - Potometer, (ii) - Porometer, (iii) - Manometer, (iv) - Osmometer

Answer 1

Hint: Transpiration is the process of loss of water from a plant within the sort of water vapor. From the soil water is absorbed by the roots and transported to the leaves via xylem.

Complete answer:
A potometer may be a device used for measuring the speed of water uptake of a leafy plant shoot. The most reason for water uptake by a cut shoot is transpiration (evaporation in plants) and is suffering from the transpiration stream.
A porometer is an instrument for measuring the world of the stomatal openings of a leaf by the quantity of a gas passing through a given area of it.
A manometer may be a device to measure pressures. A manometer consists of a U shaped tube of glass crammed with mercury.
An osmometer may be a device for measuring the osmotic strength of an answer, colloid, or compound.

Hence, the right match is (i) - Potometer, (ii) - Porometer, (iii) - Manometer, (IV) - Osmometer

Additional information:
Stomata are pores within the leaf that allows gaseous exchange where water vapour leaves the plant and CO$_2$ enters. Guard cells are the specialized cell that control the opening and closing of the stomatal pore. When stomata are open, transpiration rates increase; once they are closed, transpiration rates decrease.

Note:
 Organ donation requires transplanting healthy organs and tissues from donor to donor. Data suggests that donation from one person can save the lives of about 50 people. List of known organs that can be donated are:
> Internal organs such as kidneys, heart, liver, pancreas, intestines, lungs.
> Skin
> Bone and bone marrow
> Cornea
People of all ages and backgrounds can be an organ donor. If a donor is minor (below 18 years of age) then on the consent of his/her parents/guardian he/she can qualify for organ donation. Interested donors above 18 years of age just have to sign certain qualifying documents and he/she is eligible for organ donation. But before doing so, one must inform and take the confidence of their family.
