Question

Match the items in column I with those in column II

Column I	Column II
(a) Xylem	(i) semi-permeable
(b) Phloem	(ii) permeable
(c) Cell membrane	(iii) downward flow of sap
(d) Root pressure	(iv) upward flow of water
(e) Cell wall	(v) guttation

• A. a)- (iv); (b)- (iii); (c)- (i); (d)- (v); (e)- (ii)
• B. a) - (ii) ; b) - (i); c) - (v); d) - (iii) ; e) - (iv)
• C. a) - (i); b) - (iii); c) - (iv) ; d) - (v); e) - (ii)
• D. a) - (iv); b) - (i); c) - (iii); d) - (v); e) - (ii)

Answer 1

The correct option is A a)- (iv); (b)- (iii); (c)- (i); (d)- (v); (e)- (ii)

1. Xylem is a type of complex permanent tissue that is involved in the transport of water.
2. Phloem is another component of the vascular bundle that transports the food material from the leaves to the other parts.
3. Cell membrane is a selectively permeable structure that allow the passage of selected molecules.
4. Guttation is the phenomenon of the exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses, and a number of fungi and it occurs due to the pressure existing within the xylem vessels known as root pressure.
5. Cell wall is the freely permeable outermost covering of plant cells.

Hence the correct option is A.
