The bulk movement of substances through the conducting or vascular tissues of plants is called:
A
(A) Translocation
B
(B) Transportation
C
(C) Cohesion
D
(D) None of the above
Answer
(A) Translocation
Explanation
Solution
Explanation:
The bulk movement of substances through the conducting or vascular tissues of plants is called translocation. The higher plants have highly specialised vascular tissues – xylem and phloem. Xylem is associated with translocation of mainly water, mineral salts, some organic nitrogen and hormones, from roots to the aerial parts of the plants. The phloem translocates a variety of organic and inorganic solutes, mainly from the leaves to other parts of the plants.Hence the correct option is (A).
