Question

Match the columns

	Column I		Column II
a	Girdling experiment	p	Growth
b	Cobalt chloride paper test	q	Transpiration
c	Cresograph	r	Unequal transpiration on two leaf surfaces
d	Bell jar experiment	s	Translocation in phloem

• A. a - s, b - r, c - p, d - q
• B. a - s, b - p, c - q, d - r
• C. a - r, b - p, c - s, d - q
• D. a - s, b - p, c - s, d - r

Answer 1

The correct option is A a - s, b - r, c - p, d - q

(A) Girdling experiment is performed for the demonstration of translocation phloem tissue.

(B) Cobalt chloride paper method is performed to demonstrate unequal transpiration on two surfaces. As lower surface have more stomata than upper surface so transpiration is more on the lower surface.

(C) Osmometer is the device to measure osmotic pressure.

(D) Bell jar experiment is performed to demonstrate transpiration. We can not distinguish unequal transpiration.

So, the correct answer is 'a-s, b-r, c-p, d-q'.
